I designed this as all other Filament Oilers seem to oil the filament near to the spool. This meant when I wanted to move the filament spool from the CTC printer to the Prusa I would have a lot of oil left on the unused filament when I unloaded it.
I don't want to put oiled filament into my Prusa printer.
This oiler was designed to work with the PTFE tube and cable guild thing designed by villamany (https://www.thingiverse.com/thing:364704) This way the filament gets oiled just before entering the feeder and hot end.
The zip tie at the top is not needed as the PTFE tube doesn't come out but I added it for peace of mind.
Yes I suck at Fusdion 360 design so this is the best I can do.
You will need to print the following:
2 x Oiler
2 x Clip
