FOB Ring for NFC Tags

thingiverse

Ever needed to carry around a bunch of NFC tags on the go? This is my solution to the problem of wanting to have my Amiibo with me when playing Breath of the Wild on the Switch away from home. After printing, I stuck the NFC tag on the back of each FOB (wrote the name on them with a marker) and color coded them based on the type. The ring is just a piece of 1.75mm filament joined with a coupler and some superglue (you could also try to fuse the filament together with heat if you are so inclined). To get the NFC tags to work for Amiibo you need: NFC Stickers (NTAG215, 30mm diameter - I got them from Tagstand.com, there may be cheaper options. More info here: http://tagstand.com/blog/amiibo-figurines-and-ntag215) Android Device with NFC Write capabilities (I used a 2013 Nexus 7) TagMo Android App and related keys (you'll need to google for specifics on how to get this working. NOTE: I had to build a fork of the main project due to a crash writing the tags, check the issues list for details or to see if the fix has been merged yet) Amiibo Figures (whichever you want to take with you - you'll use the TagMo app to back up the data before writing to the NFC tags) Print Settings Printer Brand: Prusa Printer: Prusa Clone Rafts: Doesn't Matter Supports: No Resolution: 0.2mm Infill: 20% Notes: Only print setting of note is that I had to use a raft for the coupler to keep it from coming off the bed.
