These things look awesome, RSM's are definitely on my list of things to get, and these would be amazing for them.

haha, you guys rock!

The plastic that I used is PLA, a rigid biodegradable plastic. Also, the caps are offset from the rims by a few millimeters. The way the slots are printed make them rigid yet cuts down the overall weight. They will rub only if you strongly grab them from the side of the rim.


That is awesome! When you print the first one out, test fit it onto the bearing before printing another one. You want the fit to be pretty snug. The ones I had in the video both came flying off one time after I threw the yoyo funny. It wobbled just at the right frequency to loosen and fling them in opposite directions! Scale the whole part down by 0.1% to tighten the fit. I'll make some test stacks too so that you don't have to print out the whole cap just to find out it doesn't fit.

Let me know if you have any trouble printing these. I know the gcode generator can be finicky with thin parts.


<3 Shawn. We just need MOAR RSMs now.

^Coming soon...

considering making some of these today....

Yes, please find access to a 3D printer and print out a pair! Contact your local or nearby Hacker Spaces to see if they have a 3D printer you can use.

Hey Chu,

When I contacted my buddy Ethan about printing out a set this was his response:


Do you think his set up will be able to properly print a pair?

I think Ethan's Cupcake can print it out just fine. The most critical part is getting the cap to fit snugly on the bearing. Here's a comparison of a ToM and Cupcake print to give you an idea of the difference in quality: http://www.makerbot.com/blog/2011/01/17/tom-vs-cupcake/

I'd like to share that MAKE is giving away a MakerBot Thing-O-Matic today: http://blog.makezine.com/archive/2011/1 ... -of-5.html The odds are pretty good with only about 400 entries now.

Printing me some caps today. Hopefully my 3d printer has good enough plastic on hand. Will update with pics later

Yes! What printer do you have?

No clue, it's in our manufacturing lab, and I didn't even use it, I had my buddy run me some. I'll be getting them from him monday

WAHAHAHA! Can't wait for the release!

I'm pretty sure these won't be sold here....unless someone makes a whole batch for onedrop.

True, true. But I still want some!

After a long winter break, I was finally able to get to the 3d printer!

If you send me three pairs of those, I'll send you the CODE2 first!
lol jk..but if you really want to....

I don't think I can do that They are pretty spendy to make, since we use an older printer at my school. I made two sets, one for me, and one for David and Shawn. I would be willing to make a trade of some sort, if you are interested send me a PM

Those are some nice classy white caps! Thank you for printing them. Please let me know if you have ideas for improvements (I know there's room for it ).

In my recent prints, I found that on my machine, scaling down the part to .999% in ReplicatorG gave me the proper fit and they don't fly off anymore.

I had no problem with them flying off, though I wasn't a code1 OR RSMs, they worked with another hubstacked yoyo that I had. (Aoda cherry blossom) and worked really well for palm grinds. I don't own a code1, or RSMs. But may be obtaining RSMs later. Though the caps will be used with my DANG, since it's only .75mm difference between the diameter of the yoyos.
