Custom design filament oiler for Prusa MK2. Works well with PTFE tube with 4mm outer diameter.
I redrew and redesign the whole filament oiler body, and it is inspired by Shii's filament guide.
Support is required for the filament guide/oiler body. Brim is recommended for the oiler cap if printed in current orientation. I believe you can print the cap upside down without brim.
Printed in PETG. Holds up pretty well on my MK2. I am sure PLA should work as well. Happy Printing.
