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.
Other than that, stuff that is so practical it is easily forgettable: wall mount for a garage door opener, Y splitter for an exhause fan, various covers and containers.
