Wall clamp for tubing 15mm

thingiverse

I used it to fix a piece of copper tube to the wall. Need two small screws to clamp and one larger one against the wall. Note: The hole is actually 17 mm, since it was originally designed to clamp over a solder fitting which has 1mm walls. If someone want a tighter 15 mm hole, send a msg or be patient maybe I come around to making a variant.
