@@itsonmm Turn it off, Not needed and show your amateur editing skills

[@warp9988]

The background music is 2x too loud. Typically people would at least reduce the music volume (called ducking) while you're talking and then bring it back up when you're not talking.

[@NeverMind353]

Loved the explanation as to why the frame can act as a triggering mechanism! Even my dumb ass understood it :P

You're smart as hell! 😜

[@So_It_Goes_]

This is an amazing way to teach people about compliant mechanisms. My friend will love to show this to their physic's class.

[@danielreed5199]

It is also a good way to teach that it takes multiple versions of a mechanism before one actually becomes compliant.

[@littlesnowflakepunk855]

Will also be an important lesson in the dangers of sharp objects

[@shottysteve]

well done! got this on my recommended page. your mic quality is fine, and good work on editing. looking forward to seeing your channel blow up.

Thanks!

[@Flynntastic]

Great design! Thanks for showing your pile of learning pieces too. Sometimes I want to keep all my "failures" for my own personal museum of growth.

Great video, very elegant design, single part mechanisms are always so cool. Now my brain is telling me you should go bigger.

[@dalusa81]

no music needed. everything else great. Thanks for the video!

[@ohokcool]

The most interesting thing to me is the section of the buckled beams that is slightly hollow on one side actually buckles into a strange shape when loaded, I wonder if it works the same without that happening. Love the video! Subscribed, also funny that you demonstrated exactly what not to do for eye safety at the end

[@KarlBunker]

What a gorgeously simple and elegant design!

[@itsonmm]

Thanks

[@averageviewer6286]

Started a print immediately. This looks fun.

[@toastermon2272]

Cool idea! For added stiffness, I'd personally increase wall count instead of infill because the outer shell has more impact on the stability than e.g. grid infill >25% :)

[@TomatePasFraiche]

A weapon to surpass kipat barzal! Love it and printed it on a Bambulab, thanks. You should ask people to subscribe at key points of your videos, you already get tons of views that could be easily turned into recurring and increasing viewers!

[@ZEBULON181]

This is my first videos of yours but, voice overs are always better

[@m1k3y_m1]

Cool video, I would love to learn more about the microscopic compliant mechanisms you showed and what they are used for

[@markifi]

the voice over format is great, although i haven's seen the other videos. tiny crossbow is cool

[@timjeffries9833]

It might be cool to mirror the design so it can be shot from both sides. That would make for quicker reload and double the mechanics lifespan.

[@Wurlipurili]

good voiceover, mic is pretty good already, had no troubles in the headphones

[@AmericanMaking]

Very cool concept, and I love the implementation.

[@masondawson4061]

Thanks for the video and print. I've got some CF PLA I want to try it out with. That should work really well.

[@BRUXXUS]

Yay! A cool new channel recommendation! I'm going to try printing this with ABS, ASA, PETG, and polycarbonate! I predict the PC version will work best. Stiff, tough, and very low creep. 🤔 Awesome video. Looking forward to seeing more!

[@davidcat1455]

Wonderful video. The music absolutely sucks and is also way too loud. Dump the music and you’re on a winner

[@itsonmm]

[@kilobytecache6192]

I didn't mind the music but yeah it's a little loud, didn't realize this was your first voiceover until you'd mentioned it so good work nonetheless, thank you!

As for a mic I recommend getting yourself a used blue snowball. You can probably find one untested for arround 25$

awesome to seeing somebody still rocking an up box

That printer is 6 years old with thousands of hours of printing and still works great!

[@yeahright3348]

@@itsonmm I still have mine but haven’t used for six months. Compared to the Bambu x1c, the biggest differences are the better bed probing/levelling, and multifilament capabilities. However the supports on the up box/up studio were really really well dialled in, I don’t think the non up/tiertime community understands just how good supports can be.

[@FrankieJizking-js3yv]

The voiceover format is good. Also, can you create a game that involves tying a tiny filament on a fly's leg and see how many toothpick shots it takes to get him stuck to a dart board. It would make a great video.

[@itsonmm]

Thanks! I will put it on my list of ideas

[@leorocket]

could you tell use witch filament you used ? ABS seems to be a non functionnal right of the printer, I needed to bed the springs a little by hand

[@fridolineckerd6135]

Can you design a crossbow/slingshot that is increasing it's load Ina binary way. Like you pull back one soft rubber, at the end of the pull you add a second soft rubber from the opposite side. Now the first rubber helps you to pull that one back to the first side where you ad third rubber but the second rubber is helping you to pull back two rubbers to the other end where the fourth rubber is waiting. And so on and on untill you can draw weights you wouldn't normally be able to do pull.

PLA!

[@lerikhkl]

I usually don't like 3D printed toys and "trinkets", but I've got to try this!! Also regarding the video, it was very well made but as someone else said, the music is too loud. I think that a lot of makers nowadays use no music at all in their videos, which seems to work better in my opinion. It can feel very empty though if you don't have sound for all your clips! Anyway great job!

[@itsonmm]

Thanks! Maybe I will try without music at all next time... But it means that I will need to talk more, and talking is a skill I still need to practice 😁

[@Roobotics]

I wonder if the spring would be stronger if printed as a singular thick extrude per leg, or if layering them at smaller extrusions to make the same thickness, is better? 🤔 I'm actually not too sure, sigular extrudes would make a solid squished pipe type formation, while multiple lines would be more like a lattice and often have gaps. I think the reason some of your legs deform is that lattice has issues where it tried to join adjacent walls irregularly, hence the idea of printing that area as one heavy and slower extrude.

[@JMPDev]

Very cool, thank you for sharing this neat design! My only voiceover feedback: 0:48 ‘Bistable’ = “Bye Stable” ≠ “Bee Stable”

[@ShabbirHussain-qu4ey]

How do you know how long to make each buckle and how many buckles to have?

[@itsonmm]

Great question, somewhere, there is a formula that outputs the curve function of the beam. But it gives only the minimum curve needed to keep the beam buckled without snapping back. in the crossbow case, I wanted it to be powerful so I "manually" adjust the curve... I printed many revisions

[@Linlds21]

Hey man, this is a really cool project and I enjoyed watching your video, but there is something about the audio that makes it hard for me to hear your voice. I think the music was too loud compared to your voice and that the recording of your voice itself was too bassy.

Thanks I really appreciate your input. I never headed to the voiceover with music before so I have a lot to learn... I think the problem with the sound is mainly because I used my phone to record it.
