After trying some previous models that did not allow full movement of the extruder when near the top and evaluating others that replace OEM parts with newly designed ones decided to make my own from scratch trying to overcome all the shortfalls of previous models.
Instead of a single part, there are mirrored left and right brackets and each bracket is composed of a top and bottom part that is joined together with a M3 screw of at least 10mm (if you assembled the MK4/MK4S as a kit you have plenty left)
Having each bracket in two parts avoids putting pressure on the part and risking cracking it while attaching it to the frame (as it happened to me many times during development)
The LED aluminium channel was sourced locally (Argentina) they have a notch 1mm from its bottom, the bracket has a counternotch so they click in place. If you bar doesn't have this notch, you can try presure fitting ot you can file them away, they are only 0.4mm wide.
One nice feature of this model is that it allows for the wiring to go thru it straight to the back of the printer, this tidies the looks a lot since you dont have dangling cables or need zipties. Both sides are hollow, so you can power the lighbars from the control board or the power supply.
To screw both parts its better to use the M3 screw to form a thread on the bottom part and then assemble everything, this way is easier.
Hope you like it, if a mod is needed please let me know, I'll try to make it ASAP.
Printed it with PLA (Prusament that came with the printer), 0.2mm layer using organic supports (supports only for the cantilevered part of the brackets) Used the input shaper beta in the latest firmware with perfect results and almost 50% less printing time.
