This is Garmin Vivoactive 3 Smartwatch / Sportwatch holder for your bike. It allows you to mount Smartwatch on the handlebars with aid of 2 zip-ties. Smartwatch is strapped on the holder the same way as it's on the hand. It provides nice view on the watch so you can use it as speedometer etc. and it also gives a watch some protection. It's superlight design and can be printed with ABS, PETG or PLA. The zip-tie holes are hidden, making the design even cleaner.
It fits most tapered bike handlebars. In case you need to modify it, there is also .STEP file attached.
It works really well and it's tested design with 500km+ of MTB cycling.
4 perimeter shells, place it on the side with smaller handbar hole, use supports, but not inside zip-tie holes!
This is optional post-printing process that makes your 3D print looks great!
