This a project I have been working on for some time now: a 3D printed wallbox for charging our electric car. It consists of a fixed base part with all the electronics and wiring (EVSE board and 32A contactor/relay) and a cover on top. The design takes a small DIN rail inside to accomodate all required parts - plus a fuse holder and a switch on the side. Currently it is designed for a fixed type 2 charging cable.
My goal was to keep the wallbox very compact, its outer dimensions are only 160mm x 160mm x 90mm
The picture shows Wally 1.0, which has been on duty for almost a year now. Printed in PLA in black and blue.
The plug holder/rest from the picture can be downloaded here: https://www.thingiverse.com/thing:2705321 and the EVSE DIN rail holder here: https://www.thingiverse.com/thing:2723086
If anyone wants to build one, just tell me. I can deliver a list of parts which I used.
Support is recommended, since the rounded curves on the top/bottom of cover/base render a pretty steep overhang, which my printer could not handle properly.
