Watch strap retainer band for the Garmin VivoActive 3/4 (also tested on the Garmin Venu strap). Should work with most 18/19mm silicon straps.

Two files are available:

• Garmin VivoActive Watch Strap Retainer PLA.stl
• Garmin VivoActive Watch Strap Retainer TPU.stl

The first has a shallower nub to catch the watch holes. If you're printing with a rigid filament (eg. PLA, ABS, etc.) then this leaves enough space to move the retainer and still catch the holes. If you're printing with a flexible filament (TPU), then the second file has a longer retainer and provides a better catch on the strap holes but you need to flex it a bit to release (like the stock retainer).

Designed with a flat edge to be printed without supports. Even when printed with rigid filament, the sharp edge remains comfortable for me.
