Design
Measured off the OEM junction box cover to your left. Next a painstaking exercise in OpenSCAD scripting.
The previous installer didn't realize that the covers are mirrored, so they cut cable holes in both covers exactly the same. 🤦
In case you need only one cover, be sure to check which one ("A" or “B”). The actuators have asymmetric cable pass-through holes.
The model was designed for one actuator and then the STL was mirrored in PrusaSlicer along the Y axis.
The design allows for a 16mm flexible conduit for power cable protection.
Printing
Since this part is to be typically outdoors the material must withstand moderate heat and UV from the sun. Prusament PETG worked fine for me, using the “0.20mm Quality” preset with supports on the printing bed enabled.
Post-processing & Assembly
After printing the supports must be removed using e.g. wood chisel.
The original mounting screws are reused.
The galvanized flexible conduit I chose to protect the power cable was degreased and glued to the cover using neutral silicone sealant.
Another option for holding the conduit in place is to drill a couple of holes in the strain relief and use a couple of smaller self-tapping screws to bite the conduit.
