This is a simple, lightweight two-part mounting system designed to attach Prusa OpenPrintTags to any filament spool – and reuse them once the spool is empty.
One part is glued directly onto the spool, while the second part holds your OpenPrintTag. With a small twist, both parts lock together securely.
When a spool is empty, just twist to remove the tag holder and attach it to the next spool that has the base part glued on.

The model is optimized for minimal material use (only ~10 g total).
