Geoffs Solder Holder/Pen

I've had short bits of multicore solder littering my workbench for a long long time - so I liked Kezat,'s Solder Pen, but it never printed correctly for me.
.
So - here's my fully 3D printed Solder Holder/Solder pen, for 0.8mm, 1mm & 1.6mm solder

Designed to be used flat or upright.- and won't fall off the bench if lying flat.

They hold a coil of Solder inside, which is pulled out thru the "S-bend" hole, with some slight friction to stop it falling back inside - also includes a coil win
