Spool holder backing (longer lk4)
thingiverse
The back of my spool holder on my Longer lk4 broke. The spool kept falling off so I printed a new "backing" for it (if you know what the actual name for it is please tell me). The pegs are 0.25 mm in diameter. If that does not work for you, I can easily change the Diameter and upload an additional file. The center of the pegs are 22 mm apart. This "backing" may work on many similar printers, not just a longer lk4, so don't be afraid to try it.
