I've recently discovered an amazing fs2026 filament storage system and to complete the loop - I needed to feed filament from it to my MK3S+ printer. I've tried 2-3 designs form printables but didn't like any of them that much... so, I thought I can design something of my own and these were my requirements:

• maintain the biggest bend radius possible to reduce friction

• avoid Bowden tube touching any of the printer parts

• provide optimal position to feed printer from either side

• avoid interference (if possible ) with the spool mounted on the standard spool mount.

• use standard PC4-M6 or PC4-M10 fittings

...and this is version 7 of my design. I print it in PETG-CF (only because I had it loaded) but this is not a structural part, so any plastic will do. There are left and right versions included but you may also try upside-down configuration... 

The piece is probably over engineered for what it is, but I value designs that are not just practical but also look appealing and feel nice to the touch, so there you go :-) 

Post Processing

I highly recommend chasing threads with a tap if possible... printing threads in this orientation is less than optimal and it may work okay if your printer is well tuned - but Imine is not :-(
