Sunlu S4 Filament Mount/comb

you need:
5x M3 insert (standard voron size) 
2x M3 Cylinder bolt 12mm
3x M3 Button screw 10mm
4x Chinese push fittings (4mm → 4mm)

Printed in PETG, with supports (prob not needed)

the length is waaay too much, if anyone has a good filament buffer for 4 filaments that isnt costing over 150€ please share with me
