Towel Ring Screw-Closed Wall Post
This is a replacement wall post for a bathroom towel ring whose small retaining tab has snapped. The top of the ring drops into a 10 mm wide open-top cradle (fits ring wire or tube up to about 9 mm), and an M4 screw across the mouth locks it in. It mounts with two #8 pan-head wood screws through 4.8 mm holes 62 mm apart. It is 56 mm deep, 80 mm tall and 22 mm wide, and it prints on its side so the towel load runs along the layers, not across them.
