Mynt3D Spool

This is a remixed design of Bmanx2000's spool system. I scaled up his spool as I use more filament as of late, and designed the rest around my 3d pen.

The only issue I've noticed with this design is that I need to unplug the pen in order to change spools. However I've found the main support is too weak if I extend it, and I have to keep the spool rather close to the pen in order for it to unspool properly.

I don't find much of an issue with it to change spools anyways as it heats up very quickly.

In his own words

'This device allows you to store and use lengths of 1.75mm filament for a 3D pen. The unique mini spool is designed to prevent the filament from unraveling under its own spring tension. The parts can be welded together with your 3D pen.'

I've printed this with 100% infill to add strength for the spool, and because of my printers bridging capabilities I needed support material.
