10 mm band extension for Razer Nabu.
Spaces included for 2.5mm (0.1") x 2.5mm (0.1") cylindrical magnets to be inserted. (
one example found here).
Test prints have been fit to bracelet. Matte Black Steel can probably be used without magnet inserts as existing magnets hold if fairly well.
Socket of both test prints is a little tight and could be loosened with a little sanding/filing/drilling.
Have uploaded new model after printing that is 0.5mm shorter as test prints ran a little bit tall.
