Prusa MK3S filament guide for heated Dry box
thingiverse
This is an old design of mine that allowed me to consistently print with PETG using a filament dryer. It uses slotted M4 nuts and M4 screws (I don't remember the lengths). I always considered redesigning but due to its reliability I just never really needed to. I probably have 1000+ print hours running this. I even use it for ninja flex TPU with a shore hardness of 85A. This bolts onto the Prusa MK3s using some unused M3 holes on the frame just above the electronics box. I use some push to connect (one-touch fittings) that thread into this design. I just bought a cheap kit from amazon that had the stuff I needed.
