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
