Replicator 2 Active Cooling Fan Mount w/Threaded Inserts

thingiverse

Remix of a great remix, but my screws did not bite into the holes, so I added McMaster Carr metal inserts for serviceability. Use McMaster 94180A333 Heat-Set Inserts for Plastics M3 x 0.5 mm Thread Size, 6.4 mm Installed Length. https://www.mcmaster.com/#94180a333 Press them in as far as you can go, then give it a little soldering iron heat to melt them into place.

Even tried it in Fusion 360. Messed around with boolean in MeshMixer, but it wasn't clean. In the end, this is what worked best: I'm not much of a surface editor, so I imported the STL in Inventor 2017 as a mesh, created the inserts as hole plugs as a solid to line up with the mesh, then deleted the mesh, exported just the solid as a STL, then did a simple difference Boolean of the original STL file and the exported holes in openSCAD. The hole plugs have a step for the head, and is tapered 2° per the drawing.
