About this 3D model

I designed and printed a these parts to mount a wooden dowel into a nook next to entrance of my apartment. I designed it for a 35 mm diameter dowel (the nominal diameter of the hole is 36 mm), but other sizes can be used (1.25 inches is probably the closest Imperial). Includes 3 holes for screw mounting, these are sized for M6 wood screws (nominal hole size is 7 mm). 1/4" diameter or reasonably smaller wood screws should be sufficient. There is a 5.5 mm (0.22") hole for a small wood screw to secure the dowel in place, if you do not want it to roll.
