For this gantry mount you're going to need:
I predrilled the camera mounting holes with a 1,5mm drill and screwed the M2's straight into the plastic.
I used a M3 tap to make threads into the plastic for the strain relief.
The ribbon cable can and needs to be folded (slightly) twice to make the turn towards the strain relief.
The ribbon cable can get pinched after one specific set of moves, but so far as soon as this kink is made there's nothing to worry about and it won't get pinched again.
I moved the gantry all the way up and back to determine the needed cable length in the chamber as can be seen in the pictures.
(UPDATE)
It's been over a year since i made this mod and it's been running without any issues what so ever. High accelerations, speeds and temperatures give no issues. Gadget failure detection also works fine from this perspective.
Don't forget to post a make and give this model a rating, I love seeing those!
