Designed to be printable easily. Does require supports for the rear cable slot and front where the main holder branches out, due to them being perfectly straight lines that would otherwise be printed in thin air.
I've provided a STEP file as design is fully parametric and can be edited to suit other similar models, or for remixes.
Gcode and 3mf provided was what produced the attached photos, only for Mini as that is what I used and can verify works.
Fits this watch (sold in Australia as KidsOClock, but may have other resellers in other countries)
The author marked this model as their own original creation.
