About this 3D model
Apple watch charging stand. The design is modular so I should be able to adapt it to other chargers, including other watches if anyone is interested. The base (blue bit) is optional, I used a flexible filament to hide the hole you fish the USB cable through and give it a little grip on a table surface. You can also print it in a regular material, should have enough tolerance. The charge holder is not glued in these pictures, The guide post/hole solution provides a good connection... at least on my machine. Your results may vary. This was done on a stock CR10s so nothing special.
