this thing seems to be having quite the attention so i uploaded the STEP file if u wanna play with it.

gl,hf.

just a cable raceway. 155 mm long i think. (nope, 159mm long) dont really remember.

print shitloads of the hooks and assemble them.

with a tool . your fingers may get hurt after you assembe a couple of this.

width is 21.1mm . scale horizontally as you see fit.

every base has 3 holes . (no, actually 4 )

tried with a vertically printed version all-in-one and it delaminated easily , this version when assembled is incredibly strong.

view online and download , do whatever as you may see fit : https://a360.co/2w4f7iO
