Description

You may have found a new use for that Prusament spool, but what about the OpenPrintTag MK1 still stuck to it? Peel it off and put it to work again!

These OPT tag holders have an exquisite and satisfying snap-close mechanism inspired by some 2000s vintage CD cases I had laying around. It (optionally) uses a living hinge that seems to work best in PETG.

Just check out that NICE closure sound gasp!

Being open-source and reprogrammable with ease, you can continue to use these NFC tags for a variety of things beyond 3D printing.

Consider a use case where your spools (regardless if they have OPT or not) are dispensed remotely; in a dry box perhaps; yet you want to quickly boop in the data to your printer. You could have a series of "standard" tags for reference and quick scanning ready on your Prusament pegboard!

Printing:

  • Designed for 0.2mm layers. 

  • Normal/Balanced preset.
