I use a number of Polymaker PolyBox II filament dry boxes, which of course means I am no longer using the Spool holders supplied with the Prusa I3 MK3 Printers.
This led to two problems, how to feed the filament & how to overcome the friction that is introduced with the drybox that leads to under extrusion.
This solves both. it clips to the top bar of the printer just like the factory spool holders.
Just cut a section of the plastic tube supplied with the polybox (or better still replace with 8" of good quality PTFE tube (the stuff supplied with the polyboxes is garbage) and push it through the supplied drybox rubber outlets. You only need enough to get you out of the dry box.
This will work with any drybox of course.
