RFID tag adapter for spools without RFID tag

I have filament without RFID and I would like the CSF to recognize my spools.

So I made a RFID tag adapter that fits in almost any spool, it it's a bit loose you can print the wedge (orient it flat) to make it snug, the RFID tag is protected becouse it is not exposed to the rotation in the CSF, it's pointing towards the spool so it's protected by the spool.

I bought a few square tags, and also some round tags so I made adapters for square (30x15 mm) and round (25 mm) tags.

You can also carefully peal off the tags from the original filament with tags and stick it to the adapter. I used electrical tape to make sure it was staying on there.

Then you can rewrite the tag to fit your filmament with the increalibly handy app “RFID for CFS” by deusrexdesigns found here for Android: https://play.google.com/store/apps/details?id=com.lot38designs.cfsrfid
Maybe it's on Apple too, but I don't know, I don't own Apple devices.

You don't need 2 tags on the spool, you just need to have the tag on the side where the CSF's RFID reader is located, there are 2 readers in the CSF, 1 between slot A and B and 1 between slot C and D.  Just mode the adapter to the side where the RFID reader is and put the filament in the CSF to recognize your filament.

I added another version called “RFID tag adapter round small” for the thinner holed spools like the spools designed by country66 on Creality Cloud: https://www.crealitycloud.com/model-detail/678427b3ccf5567488e468d0
