shower wall bracket

Recently, my shower wall bracket broke, and to print it, I had to order a new one. The one I had was broken, but I made a 3D model based on the new one. It's not a complete set, it's missing the threaded part that screws onto the walls and the threaded nut, but these parts don't break. When I find the time, I'll edit it and add two more models; one photo is for comparison.And the middle hole has no thread, the diameter is 7mm, originally there is a plastic screw with thread, I recommend screwing in a regular metal oneTube hole diameter 22mm
