I’m learning Autodesk Fusion 360 and last night tried out its feature to thread a hole. So today I printed this 1 inch block (notice the nicely rounded edges) with 1/4-20 threads in it. The bolt screwed easily into the hole while it was still on the printer, no retouching required. I printed this in ABS plastic with a 0.1mm layer height.

Good work!

WOW!

Nice! What slicer did you use?

I used Simplify3D with a settings file optimized for the Makergear M2 provided here: http://www.thingiverse.com/thing:269637
