This is an escalable, modular, complete system to guide and hide wires on a 3D printer, using a 2020 or 2040 alu profile, but you can either use it on a 3030 aluminium profile, could be either used without a profile simply making aligned drills, the intermediate sections could be easily changed to the height you need, simply changing only Z scale in your slicing program, the union clamps must be placed centered in the joints between every two parts, more couplings, boxes, etc., at the ends, could be easily designed to fulfill your needs.
Recently introduced the new set of cable trays wider than the original ones, the first ones were made in 20 mm. width, and the new ones are 25 mm. wide, new models of clamping devices added too.
The author marked this model as their own original creation.
