The watercooling loop in my computer needed the two tubes to the CPU block to stretch quite long, so I designed these "combs" or clips to keep them parallel, and therefore looking neater.
Designed for the 10/16mm variant of ZMT, and for a centre-to-centre distance of 25mm, which matches my EK Quantum Velocity CPU block.
I printed mine in PETG (addnorth Pro Matte, to match the tubing somewhat), but PLA works just as well. I used a 0.4mm nozzle, 0.20mm layer height and enabled ironing (to fix the otherwise quite messy top surface).
(Update 2023-08-20: Minor changes to make sketch fully constrained.)
