Inspired by the planter, I used the Fusion 360 file as a basis for heavily modifying it into a stand for Samsung Galaxy Watch.
Included are both a top for Ø 34mm and Ø 30mm Samsung charging pucks. I have only printed the 34mm myself. I use a bit of double-sided tape to keep the puck in place. The snap-lock mechanism for the top/bottom parts could be better. It does the job, but not very durable or user-friendly if you want to remove the charging puck regularly.
The bottom has a hole for a M24 nut (should be available at any decent hardware store). This is for adding weight to the stand. As the outer dimensions of these nuts might vary, some adjustments of the model might be necessary for a tight fit.
The large ears makes it a bit cumbersome to use with watches with a looping strap.
Top and bottom should be printed separately. Both the bottom and top parts are designed to print without supports. I have used PLA, but should work fine with whatever. The "buttons" can be printed using MMU together with the bottom part, or separately and glued on afterwards (faster and easier).
The Fusion 360 file is included for anyone who would like to improve on the design.
