Lumber Rack Standoff

I lost one of the standoffs for my lumber rack while moving it, and printed a new one. AFAIK, all the lumber racks are pretty much the same, so this will most likely work for any of them. The recess will accept a 24.5mm wide tube and the standoff will hold the vertical bar 16mm off the wall.

No special instructions for printing (you honestly don't even need that much infill)
