Hot and Cold pipe marking and pipe spacers

During the kitchen restoration I have been worried I would make a simple mistake and mix up hot and cold water pipes. 

This small set of clips helped me to make sure I don't du such a silly mistake.

Further more I wanted to maintain parallel gap between pipes and as I'm not plumber by trade and lucking the skills and experience I have created a small aid to help me with achieving decent finish on my pipework.

These clamps are designed to fit standard 15mm copper pipes. 

I have made them from PETG and that is also the material I recommend to use as bare minimum.

DO NOT USE PLA on the hot water pipe.
