Modular Screw Holder

This is a simple modular organizer for screws, LEDs, electronic components, etc.The magnet space is for a 15mm x 3mm magnet (tight tolerance) but I have been using 12mm x 3mm magnets.Pause height to insert magnet is at 4.4mm.I printed without support and standard print settings (0.4mm nozzle, 0.2mm layer height, 15-20% infill, and 1-3 perimeters) anything should work. :)They are very useful and you can even use up scrap filament to print them.
