Here's a quick remix of mwu's RJ45 receiver to make multiple receivers in one block. For my purposes, I plan to screw the whole unit to a wooden base (joist, etc) so there are screw holes in between the modules for a wood or drywall screw.
In order to customize, edit the open scad file and change the call to 'multi_reciever'
- receiver_spacing is width of the reciever plus the solid material in between
- number_of_modules is the number of receivers
- hole_dia is the diameter of the screw mounting hole
Included is a model with 4 receivers, 25mm spacing, 5mm diameter screw holes.
