Swivable clamp for rods

I created this clamps similar to those that can be bought in some markets. I just improved it a bit to make it easier printable.

It is designed for 16 mm rods.

Printed as separate parts. When slid together and then swiveled they are locked so they do not come apart.

Clamp B should be printed with supports.

I used 0.2 mm layer height and 100% infill. Printed with PETG

I believe in free designs therefore I added also the FreeCAD file. You can easily change the dimensions if you need different sizes.
