Using same principle as Parametric delta bar clamps I designed a minimal mount for spool on a delta printer, you just need the 3D printed part and a piece of threaded rod
You can enhance using parts from Parametric universal spool holder
The uploaded file is for 8mm or 5/16 threaded rod you can adjust it using openscad or Customizer on Thingiverse

The author marked this model as their own original creation.
