Strut channel (Unistrut) parametric pipe clamp

Parametric pipe clamp for strut channel (Unistrut). You can set the pipe outside diameter and the bolt hole size. (If you download the f3d file, you will see other parameters you can adjust.)

In the photos you can see examples of ½ inch PVC (0.84 OD), 2 inch PVC (1.9 OD), and a 4 inch conduit on the wall I use for my dust collector. 

I printed in PLA and it works fine, but you may want to consider another material depending on your use case. I would not recommend using these for any critical infrastructure regardless of the material.
