Half inch hose clamp

This is a simple clamp for attaching 1/2" OD tubing to a wall or ceiling. Printed on a Lulzbot Mini with a .4mm nozzle with Innofill3d ABS Fusion+. The ABS is flexible enough for the clamp to flex around the tubing and not snap.

It is sized be 1.6mm thick using 2 walls making it solid. The screw hole is 4mm so I didn't bother with supports. Besides it doesn't need to be pretty.

I'm using these to support 1/2" OD air hose in the garage. I've also uploaded the FreeCAD file. I'm pretty new to FreeCAD so I'm sure there was probably an easier way to model it.
