About this model

When I'm not using the MMU on my Prusa MK4S I like using an external filament dryer for the currently used spool. Up to this point I simply inserted the PTFE tube from the nozzle (4mm) directly into the one from the filament dryer (6mm). They fit perfectly into each other, however the filament would get stuck on the lip of the 4mm tube. Because of this I created an adapter which smoothly transitions from the larger tube to the smaller one.
