This holder fits Apple watch 6, printing with carbon filament makes a nice finish, wood also look great.
Printing in a slight angle avoid using support in the back.
I included a sliced file for Prusa mini, it is printed in an angle to enforce all supports to be at the bottom of the print, also I applied 70% infill to the curve area which will suffer most of the stress. The rest of the print ins 15% infill.
Update 19/12/21 - bottom has been smoothed out to accommodate supports and easy removal of it.
