thingiverse
This is a little plug that allows you to drop in a 3mm magnet, then push it into foam with your thumb in order to connect modular pieces.The magnet will automatically flip to the correct orientation to align with other connections and it stays firm without hot glue (especially if you seal it with mod podge and paint etc.inspired by the modular system from https://www.youtube.com/@RPArchiveOfficialand my utter hatred of aligning magnets and hot-gluing things
