About this 3D model

you'll need (5) 4x2mm neodymium magnets to complete each piece. they press into each hole (i just used the side of my leatherman to press them in on a table that i don't care about). print settings won't matter a ton; you can make them as strong or weak as you like, though i'd suggest at least 2 wall loops. PLA is sufficient. i came across something like these that held significantly larger magnets than what i had on hand so i made these. these are intended to hold fabric down to the print bed during 3D printing.
