The quick fit carriage is just great , but the cable and the board are just not supported!
This is my solution , the Part A will mount to the back plate , and when the plate is fixed to the carriage you can screw the part B to the A
THIS SOLUTION WILL BLOCK THE " QUICK " REMOVAL OF THE BACK PLATE
but in my opinion , you don't need to move it that often and 2 screws are easy enough to remove .
the front plate is totally unobstructed but the hotend cables may need to be increased in length
to fit the Part B to the Part A you need
m3x10mm ( a little shorter will work too )
m3x8mm ( a little shorter will work too )
this version will use 3 holes in the back plate if space is a problem I can remake it with just the top 2
the notches are used to secure cable ties , I will tie first the cable alone , clamping the black tube with the cables and than i will use the protruding part of the cable tie to secure the others to the parts A and B
