Da Vinci Mini - Spool- and Tag-Holder

When I bought my printer, I also bought some spools of filament. Most of them came with the inner part, that holds the NFC-tag, but one came as a refill package without the tag-holder.
So instead of changing the tag-holder everytime I wanted to change the spool, I decided to print a tag-holder for that refil-spool.

Depending on how exact yout printer prints, you might have to file down the inner part to fit it into the outer part.
