Snap Fit NFC Keychain

Make your own NFC Key Chains

I needed NFC keychains that were branded as give aways. I looked at some that were available and they either required print pausing or the snap fit wasn't tight. So I made my own and decided others might want use it as well.

I have 4 profiles released with this. MakersJustMake branded, and blank for you to embed your own logo. Each type comes in 2 formats, tight fit, and relaxed fit. Tight fit will require some sort of pressure to snap together but it will hold very well. Relaxed fit can be done with just your hands; however over time it may come loose if you dont add a dab of glue.

These are pretty simple but I've added a quick video on putting them together, and programming them. 

Ive tested these with filling the plate and they print just fine if you need to do them in bulk. Ive made mine to use the minimum amount of filament switching (4 switches) for a clean image at this small size.
