Yeah, both options sucked.
I tried some random fuckery to try and make stuff work but it ended up stressing the wires to leave me with this:
I ended up trying out @SBS 's 3DP Puck receiver enclosure on thingiverse:
Unfortunately it just so happens to be made for a puck receiver not a VX4, back to the drawing board.
I used his version of the box as inspiration and made it in the dimensions I needed for the VX4 receiver. As well as making it a bit thicker and adding the screw holes in the base (yes I can tell the screws don’t actually have enough room for any kind of head, I need to fix that)
Installed with a bit of Butyl tape around the lid and silicone sealant around the other problem areas.
So far so good.
