Wheel with Cylinder Bearings V3 by cymon Dec 11, 2012

Description

Versions 2.2 by Thex1138 just didn't work for me. After increasing the size where it contacted the build platform I got it to print, and then the bearings fell out when I used it. In frustration I increased the sizes of the bearings. They sometimes stick after printing but a little twist and they crack free and works great.

Oof.

I'm very tempted to try coding this in OpenSCAD, to make it a reusable component. Perhaps as an xmas project? :-)

Nifty. This makes all sorts of things printable! How did you model it?

I'm hoping to make some moving components by having small connections that can be snapped to release them so that they can then turn freely. Could you tell me what is the smallest thinnest connection I could get away with?

The general rule is you need a 0.2 mm gap which tends to leave things loose. I broke that rule here on points only because I'm dealing with curves and therefore they don't have a lot of contact. Never ever break that rule with parallel surfaces.
