Mechanical engineers here. The pinion gear needs to be made of a metal harder/tougher than that of the bigger gear. The reason is, the pinion gear goes through more wear/stress/strain cycles than the bigger gear because it does a lot more revolutions. Your pinion gear should have been made with the material of those printed gears, and the bigger gears should have been made of brass. Brass is a relative simple material to machine and way less expensive. Also it wouldn't hurt to "run in" the mechanical transmission first with no load, for about 10 full min or 30min if you want to be absolutely sure the gears come the their nominal geometry and engagement. I am not trying to be annoying or anything, i just want to help out. To sum up: Pinion gear material > Bigger gear material. (hardness/toughness) Run the transmission for 10 min with no lube at half the max speed. Finally clean everything and lube up. Edit: (try using prime numbers of teeth for each gear, so they do not developed a wear pattern that could result in one or more teeth to fail sooner than the rest). Cheers.

Protecting against the sand and dirt is a really good idea. Sand is mostly silicon oxide which is VERY hard, it is harder than any metal. Your gears stand zero chance against sand. One possibility is to have rubber seals around your protruding shafts (like the ones used to protect wheel hub bearings or transmissions on cars or hydraulic wipers).

@1:43 A 3D-printed part should hold water. If _sand_ is getting through the gaps in your layer lines, you have some serious under-extrusion issues (likely because you are asking too much of the hotend/extruder.) You can solve this by reducing extruder throughput via slower feed rates and/or smaller layer heights. 100 mm/s x 0.6 mm line width x 0.2 mm layer height = 12 mm^3/s is about where my Ender 3 V2 maxes out on PLA. If you are below this, tuning e-steps is the likely solution. Vacuum-formed chassis halves look excellent 👍

​@@StubProductions To my knowledge most steel gears are either case hardened low carbon steel (e.g. 1018 or for higher strength 8620) or medium carbon (like 1045 or 4140) with induction or flame hardened teeth. It's usually desirable to have a softer, tougher core inside the gear, with the teeth being hardened to prevent fatigue failure. In this case, it's not clear what steel was actually used (A2 is different from D2), and neither is it clear what heat treatment it received. Markforged advertises heat treatment to 55 HRC for D2, which would be sufficient to destroy any tool made of steel (even high speed steel) in short order. D2 in the annealed condition (i.e. no heat treatment) is still around 255 brinell hardness, which is tough going for a cheap carbon steel tap (I've tapped 4140HT with one- similar hardness, and it was not a pleasant experience) but well within the abilities of a tap made of HSS.

This is crazy cool. I was one of the people who asked for sand performance (even though I'm not in on the KS-backing). I'm looking forward to seeing this fully finished with a rack on top for mounting cameras and other stuff. If you really want to seal up the axle holes in the body, maybe you can try out something like the principle from RC boats and submarines. As far as I can tell, it's basically grease inside a pipe where the axle runs through - and a fine tolerance between the internal diameter of the pipe and the axle.

Something that needs saying. I'm not an engineer. I barely know how to spell it. I love to know how things work, and love to see the hard work, and to feel like I know the person who makes cool things work. My point is. This snow cat could be 3 out of 5 stars average review, but it would sell better than a 4 out of 5 made by someone else that made a better product. Why? Brand, community, and communication. Most of all. He has been making these videos, and getting to know these like minded people. He will continue to get the support as long as his community feels like they are a part of something. You are doing such a good job at this. You have a great community of people here on KZbin. I love the support you all have for each other. I don't understand most of the comments here about the inner workings of things, but the passion is here. Love it. Why do I bring this up? Other brands need to do this. People will buy and support a brand, company, and product if they feel that the passion is to just make cool stuff work using math and physics. People want to feel connected to the people making the product. See the effort put in. The failures and accomplishments. This is what a brand needs to show its target customer. Really a customer doesn't want to feel like a customer. More like a part of a team. Yeah, I'll get off my soap box. Don't know where that came from really. Just see the passion here I guess. Would love to see other brands do what's being done here. Much love to you all. Happy holidays everyone.

I know I'm late to the game here.... But for sealing the axles.... instead of using tape, here's something I learned from playing with my RC cars in Kuwait....(tons of ultra fine sand....) Moleskin. It's usually used on your feet for bunions and sore spots.... It's cheap. It comes with a sticky side. It's easy to cut. It's soft so it won't wear the shafts. And it's slightly stretchy.... so you can cut a small hole and the flex it over the shaft. I used it to see my transmission outputs, differential outputs and driveshaft openings on my 4wd RC cars. It worked extremely well on both my electric and gas cars.

One of the strengths of this platform is it having no "Top/Bottom" architecture. It flips over and simply continues hauling @$$. Having a Gimbal mounted front/rear camera system would be great for FPV through the clear shell, especially if a proper window were created for it to rest/rotate within. Don't think "What can I put on top of this?" Think, "what can I put inside of this?"

I mentioned this in your other video, it is probably too late for this version, but you had an issue with clumping in the snow. Snowcats have more space between the treads, this lets the snow fall out as it rotates around easier. If you can replicate that somehow it should help, and I don't think traction will be effected negatively.

This track seems to kick up a lot of sand, you can even see it scooping and tossing some on each track paddle. Would be interesting to know how more efficient it would be if the rear wheels were smaller that the middle set so the track sort of tapers off. In theory it should pull the paddles out more gradually instead of scooping up sand.

For the axle seal I would suggest maybe a actual automotive style axle seal or a tpu rubber printable seal where the axles are and H gasket for the larger sections with some overlap built into the printed gasket and some caulk to fill in the gaps to create a water tight seal. As far as the battery charging connection you could use a flange mount connector with a gasket or a cable with a waterproof cable grip. Also If you are able to seal the entire interior of the gearboxes then a perfect seal on the covers won't be necessary and you can easily use oil or grease as a lubricant without worrying about leaking or ingress of contaminats. You could probably even install a grease zirk so it can be lubricated without disassembly. If you were able to get a good enough seal I bet this would have just about enough volume of air to even drive on water for short distances and for sure keep the water out when going through snow. Lastly I know you already have the mold but I personally would have looked into a mold for making a continuous rubber tread which would keep tension with the elasticity of the rubber and be one piece making assembly easier.

Couple ideas for you! 1, print the steel gears larger than needed by a small fraction and run them in an abrasive tumbler to remove as much of the print line as possible, and second, use camshaft seals for an engine for the axles on the snowcat! There's lots of bearings, seals, joints, etc that are made for cars that would fit various purposes on this prototype and they can be had very very cheap because of mass production!

Wtf? You can print tool steel now? What type of tech printed those? Are they actually as strong as traditional manufacturing techniques?

Definitely not as strong as forged for example but stronger than plastic, something in between. Idk about this one specifically, but there are some 3d printers for steel that will actually have very little bit of plastic in the filament to keep metal flakes together, when the print is finished it will be put in a very hot furnace that will burn the plastic into vapor and fuse the steel together.

I think it's plastic filament with metal flakes in it. You then take the printed part and sinter it, where the plastic will melt away and the steel particles will fuse together.

Not as strong as standard machined steel, but you have all the advantages of 3d printing when it comes to shapes. The parts in the video were most likely made with the technique described above. There's also laser sintering which uses a laser to melt together metal powder layer by layer, but that's basically unaffordable for personal use.

Possibly just a rubber gasket adhered/fastened to the top shell that either over bites or inlays into/onto the bottom shell Then maybe some small circular rubber grommets/washers similar in design to the body gasket you showed us. Super awesome build, really versatile little rig!

I'd love to see more of the rover project! you could make one using this design if you wanted and maybe have it set up permanently somewhere where it can crawl around and take pictures/time-lapses and you could control it remotely, maybe it could have a mode it could go in if you lose contact, and maybe it could even repair simple issues with arms? idk it would be your choices, making the rover how you want and what you'd want it to do but those are a couple of my ideas

This is super cool. One final test you should do is test the most powerful motor/battery combo you can squeeze into the kit, because you know someone will do that and it'd be good to know where the limits of the parts are
