Replicator 2 Active Cooling Fan Mount w/Threaded Inserts

thingiverse

I created a remix of an amazing remix, but my screws didn't fit snugly into the holes, so I added McMaster Carr metal inserts for better serviceability. Use McMaster 94180A333 Heat-Set Inserts for Plastics M3 x 0.5 mm Thread Size, 6.4 mm Installed Length at https://www.mcmaster.com/#94180a333. Press them in as far as they can go, then apply a little soldering iron heat to melt them into place perfectly.

Supports: No Resolution: .2mm Infill: 60% How I Designed This STL Boolean I attempted using Inventor to convert the mesh into a solid, but it didn't work out. Even tried it in Fusion 360. Messed around with boolean in MeshMixer, but it wasn't clean or precise. In the end, this worked best for me: 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 are tapered 2° per the drawing.
