UM3 NFC Holder for Polybox

thingiverse

PVA at the back of the UM3 can cause issues when printing anything longer than 12 hours or less, prompting me to consider using a Polybox instead. I actually created my own box from a rice storage container, but it doesn't look as nice as the Polybox – it's simply a matter of personal preference. Nonetheless, I want to retain the NFC reader for added convenience. This particular print was done in CPE+ black and has a slightly loose tolerance. Printing with PLA grey yields a better fit, while ABS would likely require scaling the model and allowing it to shrink a bit before achieving a snug fit.
