Hey there, I´m hoping you like my first design here on CGTrader. I made this dock for my Apple Watch Series 4 with 44mm and it fits like a charm. I also tested it out with the 40mm version (3rd image) and it also fitted very good. It should also fit for all other Apple Watches, cause the format never really changed.
For the charger: I tried both chargers for the watch, the one that comes with it when you buy the watch and also the charger that you can seperately buy from Apple (the one with the metal enclosure. Both of them fit ;-)
I have uploaded the cover for the wires in 3 different versions which differenciate themselves in the hole-size (5.5-5.7mm) so that you can download the perfekt fit depending on your print quality.I printed PLA with a 0.6mm nozzle and supports, for the cover I took the 5.5mm version.
