Tired of sticking RFID tags on your generic coils? Do you have too many eSUN spools and don't know how to reuse them for your AMS? I bring a solution!

The eSUN plastic spools have 8 holes in the central area where we can insert this small piece that allows the RFID tag of the original BL spools to be inserted. These holes are not symmetrical and usually have small variations in size between them, so they are perfect for us to insert the piece in the one that fits best. Don't be afraid as the piece will not fall off the spool while spinning on the AMS.

TEXT/PLATES:

1. RFID
2. PLA BASIC
3. PETG BASIC
4. ABS
5. PLA MATTE
6. PLA-CF
7. PETG-CF
8. PLA Glow
9. PLA Silk
10. ASA
11. TPU 95A
12. PETG TRANSLUCENT

I want to make it clear that this has not been designed with the intention of using the original RFID tags with filament from other brands, my only purpose is so that we can use those empty eSUN spools if we do not have enough from BambuLab. If you buy BambuLab filament without a spool, you can assemble it on an empty spool and rewind it on an eSUN with its own RFID tags.

At the moment I am sharing it with you as BETA since I have tested it on 23 different eSUN black spools but only with 2 RFID tags, in AMS and AMS Lite, and I cannot guarantee 100% that it works in all situations.

The reason why I have only made an anchor to the center of the spool without another secondary one, for example to the filament insertion holes or to the other 2 central slots is because eSUN has 2 different spools with different alignment. My intention is to be able to use one version for all or release two versions. In one of the coil models, this adapter is too big for the hole because the plastic is thinner, so it must be inserted into the intermediate slot.

Modified the edge of the adapter since in the AMS Lite it hit the rotating support and this prevented greater proximity between the RFID and the reader.
