This was a Curtain rod holder bracket I designed to be used with a wood dowel. The hole for the dowel is exactly 33.5mm Diameter. Roughly 1 5/8th inches. I advise printing out the piece and bringing it to your hardware store to find the right dowel. The design also has the ability to put in a M3 hex and bolt to tighten down a loose dowel.
