Hello. I designed this magnetic holder for your apple watch charger. If you hate the way your apple watch dangles while its charging i have a solution for you. You can quickly remove your charger from the stand. 
It uses magnet 10.08mm x 20.08mm x 2.08mm.
You have to pause your print on layer 13 (2.6mm) if you print on 0.2mm layers and insert two magnets. Other 2 pauses are on layers 75 (15mm) and 226 (45.20mm). I uploaded picture how to place these models on your plate in slicer. When you print your hook for your desk it's necessary to screw it from bottom. I recomment printing PETG. 0.2mm layers and 3 perimeters for durability. Atleast use 20% infill. There is no need for supports. Have fun printing and charging your apple watch!
