An OpenScad customisable pipe clip/clamp.

You can change the following:

• ring diameter (internal / external)
• rounded ends + diameter
• mounting hole number, diameter
• countersink diameter, depth
• mounting plate depth / width / height
• ring gap
• mounting plate / ring angle
• clamp end width, height, depth, hole size

Depending on the settings you choose you might need to print with supports.

Can be printed with the ring upwards, but the layer direction means the ring arms are more likely to snap off.
