Clothespin compatible with tubular clothes lines

I needed a clothespin that would fit more than just a string line. 

Tested on regular string line and tubes ranging from 2 to 17mm. 

2 part design with spring to improve grip strength on thinner lines.

Supports should not be needed.

I recommend using brim ears to decrease chances of the long and thin parts from warping, unless you have a very good bed adhesion.
 

Printed in ASA. ABS should work without problems. PLA is untested and I suspect it might break or creep too much over time. PETG should work too, though it might grip with less force.
