Spinning Double Ball Bearings
by idea_beans

Description

I was requested by a friend of mine to modify my original double bearings to add more layers/rings to it.

It may not work as well as the double bearings, so please post feedback on how these ones print on your printers so I can make adjustments accordingly.

Thanks!

Instructions

There are 2 STL files here.

Triple ball bearings - 62 balls
Quadruple ball bearings - 106 balls

Just print and remove the raft. Give the balls a bit of pushing and cleaning, then the bearings should work right away.

Tried printing off the larger one on my Replicator, but the default support material (using ReplicatorG or Makerware) still doesn't handle curved bases yet. Any suggestions?

Hi I'm not familiar with Replicator software, but maybe someone from MakerBot can help if you ask in their forum? My UP Plus printer software allows me to choose the angle limits for building supports, so if I select 30 degree it usually gives me good curved bases when I print spheres or rounded corners. Thanks

I made the big one. It printed very nicely but the inner rings started to ''fall off'' so I can take it apart into 4 rings. It could be because it cooled off or because I moved it to much when I tried to make it move. Takes some time to get it going but it's very impressive. Awesome job!

Awesome video recording! That's a lot of balls for sure. I may have counted it wrong, 91 balls, give or take. :) What material did you use? Any suggestion on the ball size or spacing etc? Thanks
