Summary

This is emmett's cube gears, with a Triskel-style design etched into the surface.

Instructions

Print four each of the two triskel STLs:

Gear1-triskel.stl
Gear2-triskel.stl

Then print four of the Bpins.stl and one of the BcenterFlat.stl files from emmett's Screwless Cube Gears. The gears gear-surface is unchanged, and can be freely exchanged with emmett's gears.

Command I used to make the DXFs from the .ai files (which are PDFs, BTW):

pstoedit -dt -f 'dxf:-polyaslines -mm -ctl -dumplayernames' triskel-small.{ai,dxf}
pstoedit -dt -f 'dxf:-polyaslines -mm -ctl -dumplayernames' triskel2.{ai,dxf}

This is on OS X, with a Bash command line. I probably should make a full blog post on that technique.
