GraviTrax 3D Parts - Surem2804 Etsy Shop Review

I’m reviewing over 70 GraviTrax add-ons from 7 Etsy shops. In this episode, I review add-ons from Etsy shop Surem2804. Add to your GraviTrax collection with these unique parts, including adapters for using GraviTrax together with Lego!
🤠 I’m Chris from the Masked Marble. Join me on my quest to find the world’s best 3D-printed add-ons for GraviTrax marble runs! These pieces extend the capabilities of the stock Ravensburger GraviTrax sets. In the interest of full disclosure, please be aware that I received these parts for free from shop owner Karlheinz for the purposes of this review.
🛒 Buy Surem2804 parts here on his Etsy store:

UPDATE: The shop owner reports he has now fixed the height issues that are discussed in this video. Various pieces did not align well with GraviTrax tiles due to variability in Ravesnburger GraviTrax tile production, which tiles were the basis for the shop owner’s measurements.

⭐⭐⭐⭐⭐ Ratings
I evaluate each Etsy shop’s overall 3D print quality, and then review each part individually.
Parts get scored in 4 key areas:
1. Quality. This evaluates the part’s fit, operation, build quality, and ease of use.
2. Utility. How USEFUL is this part in a marble run? Does it add new capability to GraviTrax that you didn’t have before?
3. Fun. This is the part’s coolness factor and is my opinion of how much fun the part will add to your marble runs!
4. Uniqueness. This doesn’t measure how good the part is, but whether the part is an original design that you can’t get anywhere else. A generic design that is sold by several Etsy shops gets a lower uniqueness score.
Let me add a caveat: 3D printing is somewhat of an art. It’s not just the design that counts, but how you print it. Many of these shop owners are improving their designs and processes over time, so the parts YOU receive may differ in design and quality from the parts reviewed in this video. Be sure to talk to the shop owner if you have any questions. I’m simply reviewing the parts I received at the time of this video.

I love the creative variant of the ball bearing because it’s just so dead simple you just need a top half and bottom half with a channel on both halves and then you get your balls in and then it would rotate

[@Nonsensicl]

Pros of this shop: •Useful parts •Good for siblings that prefer Lego Cons of this shop: •Not very much color variation (excluding Colored marbles.) ▪︎VERY generic designs

[@Magenitech]

22:13 And then if you put some angled tiles beneath it all, it would be a leaning tower! Until of course you make it too tall and if falls over. Then it's not leaning, or a tower! 😁

[@MaskedMarble]

I should try that. I bet it would fall…

[@nicholasstanton9575]

Angled tile + the lift = Pisa

I purchased the coloured marbles, and the shipping was a lot earlier than expected! I had a Gold Marble to compare with this one, and noticed it was more transparent, and a little lighter than the official gravitrax marble.

[@PolishDude1122]

Blueberry, strawberry and blackberry jam 😂

[@GravitraxMania]

Again lots of cool printed parts🤩🤩

[@Aiden45-w]

10:16 By these Lego GraviTrax combo rail track Lego tile thingymabob adapter doohickeys… Nevermind 😂

[@brennanhorn4637]

I really want those rails, they look baller

[@MaskedMarble]

Yes, they are addictive 😵‍💫😎 and not too expensive.

[@brennanhorn4637]

@@MaskedMarble I really am intrigued by them

[@arkasha6649]

Maybe we can use trampoline height to fit smallest 1 tile special Y rail cuz of its said inflexibility.

[@darknessblades]

Would love to see a rail that spends over 1 meter

[@MaskedMarble]

There is modular rail design on Thingiverse, but I don't know how long it can go. Here's a video with a long modular rail on Facebook: m.facebook.com/groups/385232459229655/permalink/492521835167383/?mibextid=Nif5oz

[@dinhtuan752]

final part next week.

[@Aiden45-w]

How do you build the hanging gardens of Babylon in GraviTrax?

[@BalltrackMarbleRunGravitrax]

Hello, I'm balltrack, I wanted to ask you where you got the 3D shape to build on top of each other like in 22.39min. I've been looking for it for so long but I just can't find it. I need exactly this shape

[@MaskedMarble]

All the 3D printed pieces reviewed in this video can be purchased from the Etsy store which is linked in the description.

Man, so much items, so much to comment about, where do i start... The lego integration parts were the BEST idea i have ever seen in my life, for marble runs that is, integrating A WHOLE DIFFERENT TOY COMPANY is just over insane and cool, imagine using these electric lego sets, giving more logical freedom... Colored marbles are really really cool, especially rainbow, gradient is the best thing invented in colours! Id like to see a lot more gradient coloured marbles, for example: black and white gradient (aka monochrome), blue and white, blue and black, blue and red (its just my favorite colour is blue lol), blue and purple and so much more! Really wish there was a way to get FULL 255-255-255 RGB freedom, it would be the best looking invention yet! Height risers and elevation columns really do miss the ,,hollow" opportunity, which could have potentially been the best addition to just normal height blocks, and the imperfection in height actually gave me a funny idea for a new type of height block: *Micro height blocks! Adds 1mm each, so much height freedom! And could maybe fix the height issue.* Multi marble launcher sure does a lot of problems to deal with, and potential improvements, my idea of fixing jams is maybe attaching a mini door to the side of the moveable beam, so everytime its pushed it opens door in a way only 1 marble gets loaded on track at a time, not sure how it will work or look... I just have ideas, i dont have skills to make my own ideas real, most of the time- maybe give a tiny fence on the funnel, and maybe slightly make the tunnel bigger so its too much space to jam, and make some spirals somewhere so its organized. No idea why creator made beam squeeze marbles instead of push, that makes no sense... Also, maybe make a new variation of it where instead of pushable beam its powered with electricity and has electric pusher? That one that is attached to a spinning circle so it goes back and forth. Elevation tiles are EXTREMELY nice, very much potential, you could probably use trampoline height blocks to make a tilted tower you talked about. Also the part where you stacked vertical pipes on this tower really looked like a snake climbing up, could be useful for nature-themed track, if there are different decoration themes for gravitrax. All track parts that direct marbles down where this tile fits on are very cool in general. The catcher ramp is a bit sad for not being a jump ramp successfully, would have been very cool. Also connecting 2 of them together could have possibly made a combination of catcher and jump, marble lands inside 1 ramp which catches it and then it rolls and jumps off 2nd ramp, would be really cool. Volcano mixer is a very DESTRUCTIVE mixer. Maybe you could put some walls or catchers for marbles that have too much speed and roll right on top of the mixer, and since its rng you can either take advantage of it or just connect all 3 catchers on 3 sides into 1 line. Also, for the walls option, if the top is completely flat and marbles that are stationary on top of it wont move, maybe either use trampoline height to angle it so marbles roll down or ask creator to make them angled a bit so they roll marble towards closest of the 3 intended lines. Make sure to never use 1 time track parts with this freaking casino machine. ... I got an idea of actually using the mixer for some sort of slot machine: *First, use the walls method, and then make 3 intended lines fall into some narrow tube where only 1 marble can touch the bottom, and with its rng you could put different colored marbles and they fall in different orders, and 3 lines is 3 marbles on 3 different bottoms, essentially making it a slot machine.* Electric lift is much better than original elevator, 3 different entrances, with 3 exits each, on different heights, 9 exits in total, and either 1, 2 or all entrances could be used, but only same amount of used exits, not more, idk how they will physically be able to be more or less than used entrances. The original elevator is slower (i think), only 1 entrance and only 1 exit, if you need it is the smallest height tho, and (i think) doesnt require and height at entrance, where electric lifts do need some height. Also you could probably use it for aesthetic purposes, like some sort of battery, where you fill it entirely with marbles and then make exits connect back to same entrances, for infinite cycle of marbles being lifted up, i bet it'll look cool (especially with blue marbles =)). Versatile tube is very unique unlike other snake rails and tubes, cuz its viewing side is COMPLETELY open instead of little gaps and can be placed in 4 different directions. Placing it viewing side up is theleast creative variant, cuz it just looks like normal snake rail but green and with walls, however its the smoothest variant and marbles get stuck the least like that, placing it viewing side down probably could be really cool (if marbles wont fall out), cuz its entirely mystery of where marbles currently are inside of the tube, and you cannot see, placing viewing side vertically is extremely cool, how despite the teeth, with enough speed marble can still make it through, and with slecific vertical placement marble can even make it through without requiring that much speed. Also, looks like a snake and is green, so could be used for nature themed decorations. Extendable rails, i was REALLY thinking about suggesting it in some comments, but guess i was too slow, someone already made them a reality, and even better than i thought, making them potentially infinite! You can not only cross any amount of tiles with them, but also any amount of heights, which im sure is very useful, SO much rail freedom! This one especially deserves my respect here. *+* Snake rails don't REALLY seem any special, the only admireable thing is that these ones come in different sizes, but they do take marbles longer to pass through and do take more space, so they are unusable in tight spaces. I have no idea what else to say... Special rails Y are not TOO unique, other than size and being a rail they are quite normal, but the J ones are taking the cake. They are more unique with such a turn at either the end or the start, not in the middle or smooth curve, however i do see they could use some extended walls at the turn, cuz marbles with too high speed are straight up derailed. Other than that, super cool rails! Needle rails honestly deserve such name, for uniqueness of going between 2 separate tiles, allowing for a tight fit between height towers, giving it lots of potential! And even coming in 2 variants with different 2nd turn is just peak of convenience, i honestly didnt expect 2 height towers would have enough gap for rail to fit through, especially after seeing the height risers and elevation columns having to small of a gap for a rail. Quite ironic to be honest.

[@greybyboy]

Bro wrote his whole college essay💀

[@barkermarbles1498]

The Volcano Mixer felt very similar to the regular mixer.

[@MaskedMarble]

If you are referring to the splash pad insert, then yes, it’s like a modification of that, but not as reliable.

[@AngelSanchezGIVERIGGYARAISE]

I want a tile maker option to gravitrax plzzzzz Edit: its for the gravitrax app

[@HWMarioKart]

Maybe a rail can be 10 miles long!

[@AB-these-handles-are-stupid]

The normal force is perpendicular to the plane

[@BalltrackMarbleRunGravitrax]

Hello, I have a question for you, and you might have a file to print for the Elevation tile that you could give me, I really want to print this part, but I can't find it.

[@MaskedMarble]

Hi. Here are 3 GraviTrax stacking systems on Thingiverse. The first uses Lego Technic. www.thingiverse.com/thing:5459172. The second requires some modification of existing tiles and assembly. www.thingiverse.com/thing:4874250. The 3rd is more similar to what I reviewed in the video. www.thingiverse.com/thing:5159123

[@MaskedMarble]

PS. Watch the video posted with the Technitrax design to see what it can do.

[@BenSilber]

print bed surfaces look like they're all printed on a raft if they're that rough. otherwise their first layer height is way off

[@MaskedMarble]

That’s a good point. I didn’t think of that.

[@keylerfonsecagameplay3934]

My favourite gravitrax addon Is lego adapters, electric lift extendible rails and elevation tiles, but tell me why that shop Is canceled in Etsy shops?

[@MaskedMarble]

Not canceled. The Etsy store says “Surem2804 is taking a short break”. So check back, probably next week.

[@kulicka-fj6cc]

super super

[@keylerfonsecagameplay3934]

Chris, I found surem 2804

[@jadenruanes1858]

What’ll happen if you step on the LEGO adapters?

[@MaskedMarble]

It will probably hurt, but not as much as true Lego! 😆

[@arkasha6649]

Probably wont hurt as much as a single lego piece, cus its an evenly spread large area of teeth, and if its larger the pain is spread across all foot so its too little to be noticable pain.

[@mr_shark69]

I got a lift from surem that is 34cm high (its only on his ebay-kleinanzeigen shop)

[@MaskedMarble]

Nice!

[@dinhtuan752]

🤠

[@Aiden45-w]

24:10 won’t fit on a Tip tube

[@MaskedMarble]

True!

[@andrewraab8620]

What about Italy

[@chef6887]

Print quality is rated too high if I see the parts. Nice video

[@MaskedMarble]

Thanks for watching! I find print quality difficult to quantify. In some cases the quality varies from one piece to another from the same shop. I tried to approach it by comparing all the Etsy shop prints against one another, and giving them a relative score so at least people will know who has the better print processes in place.

[@Idkwholmao]

Nah, it’s lay-boh-ray-toree. Not really, of course!

Suprised i know viridian?

[@MarbleSportsPro]

Those Lego ones are epic

[@MaskedMarble]

They add a lot of possibilities!

Electric lego sets-

[@rosariobono438]

Thank you for correctly referring to lego bricks, far too many people get it incorrect and call them “legos”
