Battery Charging Dock for VEX IQ & EXP

This is a dock for charging 5 VEX IQ (2nd generation) and/or EXP batteries in an organized manner. VEX classroom kits come in multiples of 5 robots, so you can print as many of these as you need for the number of batteries you have.

The dock itself will need supports under the cable routing channels. I would not recommend using supports under the deep circular holes, as it's not necessary and removing the support material will be very difficult.

“Plate.stl” is a flat plate that goes between the main body and legs, and helps to secure the cables in place. In the photos I've laser-cut this piece from ⅛" acrylic to save print time; “Plate.pdf” is the file for that.

Additional parts needed:

- Right-angle USB-C cable: https://a.co/d/44bcDQQ. You must use this exact cable, or another cable with an identical-shaped USB-C plug. The link is a 3 pack; each dock needs 5 cables. - Heat set inserts: https://a.co/d/84c0rBL. For attaching legs to dock. The link is a 100 pack; each dock needs 4. - 8-32 screws for attaching legs to dock. Same size as used in VEX EXP and V5 kits. 1 inch is a good size; 4 per dock. - Hot glue: for securing cables in dock. What worked for me was to apply some glue to one of the recesses, then quickly pop a battery into the slot and plug the cable into the battery. Then hold everything in place for 30-60 seconds while the glue sets before moving on to the next slot. This ensured that the cable was perfectly aligned. After gluing all cables in, I added some additional hot glue on top of each cable for additional strain relief. - USB power supply – I used this one, but the exact model isn't important: https://a.co/d/37vaYuM. - The power supply is mounted to the underside of the dock with some squares of “3M Dual Lock”. Velcro would be fine too, but Dual Lock is better.
