Max great video and keep 'em comin'!

how can you do it amazing 🤩

This is the best and easiest to follow tutorial! Thank you

this is so hard!😭😭😭😭

Thank you so much i will sub to you thanks soo much

intro

how do u do it OMG!!!!

I can see from when i found this video it was going to be cool

Pritty design

Hahahhaahahahahahahahahaahhhahahahahahhahhah😂

This isn't very hard and it looks cool noice:)

Can I get the dimensions of the CAD design??

Bruh!!

😮😮ooh

i wonder if i could use this as an airsoft grenade

so BAD!!!!!!!!!!!!!

very complicated

Neat

Can you explain the purpoae in more detal.. how does this help visualise frames of ref?

You can add ballbearing to the helix and the rollers axis, then line the helaix with any hogh frixtion material . Tpu sheets or ruberbands..

I like it. Especially when you pull it back up and see the illusion of it moving back in the spiral. Now if you make a spiral wound in a circle and the rod follow the radius curve, you could turn the circle and see it continuously traverse. I'm not sure it would be useful but would be interesting.

Hey may be beneficial to mirror the audio so it doesn't sound like you're in my left ear. Nice video otherwise.

silicone caulk or rubber bands would add traction. Either that, or add a groove for an o ring.

Very cool. What did you use to design it?

Wow! Very cool. It's amazing that you understand how to do this AND you made the parts with a 3D printer. 🤯

I love u max!!!

Super cool video! Thanks for sharing!

That was intense staring down into a nuclear reactor and watching the power go from 80% to 0% in about 3 seconds! Thanks for making this video. Yes, show us more amazing things you don't normally get to see. 🚀

First🫶

It's cool to see all the lab equipment. 👍

FAKEEEEE

It's awesome seeing smart people battling it out with a good old fashion tug-of-war! It's so important to balance studying with having fun! 💪 💪

these are so cool😃

Glad you're posting again! Boiler Up! 💪

You’re a true leader and teacher glad to see you’re helping your fellow students keep up the good work

When posting projects, especially code, it is good manners /good practice to show the source of any library used. Reason being , there can be many which will not work with your program and people get pissed off as a result.

Wow❤this sooooo easy😊
