Soft Water Tube Holder

I created this water cooling soft tube holder for my desk pc so that they hold the tubes along the way from the reservoir to the cpu.
I have 3 variation of it;
6mm, 30mm and 10mm height.
these are made for 13mm tubes and the inner diameter is 14mm witch it will give a little space for the tubes to move freely.
the mounting holes are 4mm.
