Bracket for 3/4" O.D. tubes

I made this one 2 years ago and it has still held up great. It helps me cool the workstation in my office (main floor) via a 480mm radiator in the basement.

PETG would probably be the best for durability, but I printed this one in PLA and it hasn't shown any sign of risk of failure so far.

This was my first attempt at using blender (I use CAD at work), so it's not pretty, but it's functional. This was the first iteration that I actually printed and it ended up being a perfect compression fit for an old 2x4 in the basement, I didn't even have to put any screws in it.

It's far from perfect but since it fit, I never bothered refining it. Sharing the .blend file in case anyone wants to modify it for their needs and/or make it prettier. =)
