REVISED! This is the MagSafe version 2 of my minimal iPhone and Apple watch charger. My previous version had a larger body. Slightly refined to fit closed watch bands, and lower cord exit. The weight tank is filled with shotgun pellets but you can use fishing weights also.

Note: M2 hex screws suck. Use M2 torx so you don't have to deal with cheap screws that strip the hex head so easily.

Items needed: 4 M2 threaded inserts, 3 M2x4 Torx screws, weight media, MagSafe charger, and Apple Watch charger.

Printing:  Use PLA. Although I designed this model to use the least support possible, organic supports are used. 

Assembly: First, melt in the threaded inserts (tip: press threaded insert ¾ in then use center punch to press in the remaining distance for a clean install). Run cables through openings and run out back. Next, press fit the MagSafe charging puck. Snap in the watch charging puck (this will take a bit of force). The quality of the print will affect the fitment of the charging pucks, so some post-work may be needed where the supports are. Select which watch tray you want to use and install the threaded insert and screw together. One of the watch trays will have "Ultra" printed on it, indicating use for the Apple Watch Ultra. 

Additional notes:The weight tank lid press fit onto the tank and come off quickly until they are inserted into the main body, where they will remain in place after the bottom plate is screwed on. Just make sure the weight tank lid seat fully. Don't flip this upside down without gripping the base to the body so the heavy contents don't fall out. Screw the remaining M2 x 4mm Torx screws to the base, and you're ready to use. I recommend you glue the tank lid to the weight tank but if you're careful you shouldn't need glue.
