Most useful was probably this holder for two 1/2in PEX pipes. Printed in ABS, it holds cold and hot pipes in parallel, and uses a #8 screw for attachment. All commercially available holders are for a single pipe, and use nails. Hammering nails in tight spaces (and doing so twice) is not particularly convenient for me, thus, this contraption was born.
