Massive Chocofi case with M3 bolts

This is a remix of an excellent model to use M3 nuts and bolts instead of M2 heatset inserts. You will need three M3x10mm bolt. I had one brand of bolts that fit, but another didn't, so I don't guarantee that all M3 bolt heads will fit.

I only use 3 bolts to secure the keyboard because the 4th position is too tight on my board, and the J key switch was not seated properly. Note that I don't use the switchplate; maybe if you use the switchplate the bolts would get in the way, I don't know.

I uploaded both the STEP and Fusion files (kinda parametric). I only used FreeCAD to export the original model file to STEP.

Note: the picture shows 5 holes for nuts in the bottom of the case. This was my first (and current) test print, hence the change in colour partway through. I updated the source files because those holes either didn't go through the PCB or the bolt head didn't fit.

The following changes were made:

• Closed the mesh properly (the original STL was throwing errors in PrusaSlicer),
• Closed the two supports for the shield as I don't use that,
• Added 3 M3 nut slots where previous supports were,
• Other supports closed (unused).
