knitting needle caps

My grandchild asked if I could make a knitting needle stopper to prevent the yarn from slipping off either end of the needles when she needs to stop or take a rest. I looked at what was already available but did not care for any of them. So I made these very simple and quick prints.
The green were made with PLA. Stiff but they do work. The yellow was done with TPU, is flexible and easier to use.
Sized for #10 needle.
