3D pen accessories

thingiverse

I've found some accessories that have been extremely useful for my 3D pen. They essentially consist of a hanger to keep my 3D pen always at the ready, and a spool along with a spool holder so that the filament isn't constantly entwined and dangling around. The primary issue with the filament dangling around is that eventually it will come into contact with the hot end of the 3D pen and your filament becomes ruined. You have to cut it off. With this spool, this issue does not occur. In order to wind the filament, I use a heat gun or a hairdryer to slightly soften the PLA so that it stays in the new shape of the spool and it functions perfectly. All these pieces combined weigh only 35g of PLA!
