Glueless Embedded RFID Anti-Tangle Filament Clip and Mount

A multi tasking little filament clip that hides an RFID for all your sneaky filament tracking and management needs!  

This is a great print because each clip is under 4 grams and prints in less than 10min.  The mounts are also around 3 grams and print in under 8 min.

The point of this clip is to:

1. Hold filament on the spool in storage like a clip.

2. Be able to be used with the included mounts to travel while in an AMS or printing from a 4L cereal box.

3. Hold and RFID tag for the hopeful future of open RFID spools.  I currently use Filament RFID for android and can write to Elegoo, Snapmaker, etc…

The clip is designed to be able to fit into the mount that can be superglued to your AMS, drybox, etc so that you can take it off and keep the clip with the spool for storage later.  The point is to keep the mount in one area and be able to just rotate spools and clips, while having the added awesomeness of a filament clip.  

I tried to make this fit most spools, but it is not one size fits all.  It fits most cardboard spools (it is modeled to fit a cardboard Elegoo spool) and can fit a lot of plastic spools but may tight.  If you have a spool that this wont fit, please let me know and I can modify to make it work if you give me the thickness of your spool where the clip mounts.

The 3mf file attached has a pause at about ¼ of the way into the print where you will take your NFC chip and insert it.

 
Here is a link to some of the NFC tags I have used (but any NFC 215 tag should work):   https://www.aliexpress.us/item/3256808449011336.html?spm=a2g0o.order_list.order_list_main.5.6f281802lVJC2R&gatewayAdapt=glo2usa

I have noticed that some of the NFC tags are not quite the same diameter just depending on where you buy them or sometimes even the batch.  If you notice that you have some that will not fit, press them in during the pause and make sure they are flush.  If you need more space, let me know and I can try to tweak the model for slightly larger diameter tags.

To input information about the filament to the RFID tags, I use an app called Filament RFID (Android), but there are others that can do the same.  I like Filament RFID because it can code to various brands of filament. 

Print Notes:

• Material: PLA (But any can be used)

• Layer Height: 0.24mm

• Supports: I have painted supports in the 3mf file, please make sure Normal (Manual) is enabled.  You will have to pick a little at the end to get the supports out, but it is easy to clean these up.  If you print as an STL, ensure that the Normal (Auto) supports is enabled, its a bit tougher to remove, but this will not print well without supports.

• Infill: 10%, gyroid

• Walls: 2

• Pause: If you don't use the 3mf and use as an stl, make sure you add a pause to the last layer before the fill over the NFC chip.  See image for where I added in the 3mf.

Let me know if you need anything or have questions and hope you enjoy this little model.
