About this 3D model

Color order: White, Green, Red. Quick Guide to changing filament~ Have some paper to push away extruded filament. When the MK3 jogs after a change it will spit out another inch, so I follow it with paper until it starts to move back down. Doing this has given great, repeatable results. Use a tool like this to help changes→ https://www.printables.com/model/329171-filament-change-tool Have fun! At normal scale changes are 1.4 and 2mm
