The modular USB holder model didn't mix well with the Flashforge slicer, so I had to fix the model to make it work. Changed were made to remove non-manifold and loose geometry.

Print related stuff:

Print time: 1 hour 59 minutes Filament used: 9.66 meters of PLA

Estimated material cost (PLA): ~0.87 € (Calculated from 200 m spool with a price of 17,99 € ≈ 0.08995 / m)

NOTE: The dove tail fit is too tight, since there is very little tolerance. Needs more fixing, or filing the dovetails a bit after printing. Triangular file recommended.
