This is the newly upgraded version of my NATO strap adapter for the Fitbit Air! I’ve completely redesigned it to be slimmer, less bulky, and even more comfortable on the wrist.

The best part? It now prints completely support-free!

I optimized the geometry so you can print it flat on the bed without dealing with messy support removal, saving you time and material while leaving a much cleaner finish. It still prints beautifully in PLA and offers a highly personalized, comfortable (especially the 20mm version), and budget-friendly alternative to Google's official straps.
