Stopper for 3,5mm knitting needle

My girlfriend wanted to have some stoppers to stop the wool to slide off of the knitting needles when transported. So I designed these very simple stoppers that slide on the needles and prevent you knitting work to fall apart. Now you can take your needles everywhere to get these socks made for all your family members!

The stoppers are designed for 3,5mm needles but I also have a version for 5,5mm needles available.
If none of the diameters fit your needs feel free to edit the F3D file to fit your needles.

I used ColorFabb Tough PLA which offers more compliance than regular PLA and should increase the lifespan. As the deformation during use is pretty small, regular PLA should also do the trick.
