Large & flat junction box (free, + steps)

Large, electric box. Should be preferably printed from flame retardant material. Uses M4 heat-sinks and metrical screws. Designed for M20 electric glands. 3D printed glands are added to the model, however these require the cables to be wrapped in electric tape. Model uses a 3D printed sealing, however that can also be cut out of a piece of flat rubber.

Wago clamps need to be glued into the respective interface.
