Summary

Supports for 1/2 inch piping, was doing some plumbing under a deck and realized I didn't have any copper straps to achieve this function. No risk of galvanic corrosion as plastic does not react with copper or any metals really. I used PLA with 40% infill, 3 perimeters and a standard 0.4mm nozzle with 0.2mm layer height. Uses #8 wood screws, recommend at least 2" long screws.
Sized such that when the pipe is aligned with a 2x4 it will comfortably screw into the edge of the 2x4, of course the face would be wider and would work too.
Seems plenty strong in my opinion. Took around an hour to print each one.
Design file is Solidworks 2019 if you'd like to edit the model, be aware of backwards compatibility if you have an earlier version of Solidworks
