Better 3D Printable Bearing

I tried the print in place bearing from bribro12 (https://www.thingiverse.com/thing:2349065), but on smaller bearings like skateboard size, I found the rollers twisted out of place and jammed up. Instead I moved the fat parts to the outside and that keeps them in line.This also seems to make them easier to free up after printing.

I uploaded 3 popular sizes. The larger two print pretty cleanly from me. The small one needs a little care to work in after printing. Don't expect these to be a replacement for real bearings, but they are good enough for mission critical components such as a gimbal stabilized beer holder (https://www.thingiverse.com/thing:2727133)

Update 1/19/18: So I uploaded this because I thought a few people would have a passing curiosity. It got more hits in the first few hours than all of my useful things put together. I tweaked a few dimensions, put a chamfer on the outside so you don't usually need a raft to print and provided more clearance in the center of the
