Dowel like thing
thingiverse
MakerMatea created this design: http://www.thingiverse.com/thing:1033222, an improved version that makes my own project obsolete. It's still untested, but I'm eager to try it out as soon as my printer is back up and running. A dowel-like item for 20x20mm extrusion that fits perfectly with M3 bolts.
