Works for screws that are approximately 4.5mm in diameter. You can customize screw_diameter
and other parameters in the f3d project (Modify → Change Parameters).
Print without supports. Use some of the more heat-resistant types of filament like PETG. I used the fireproof FrJet PLA by Filament PM. I’d be interested to hear which materials worked or didn’t work for you guys.
As always, honest feedback is welcome. Happy printing.
