Ender 3 S1 filament spool holder with bearing

This spool holder is universal (for 20x20 profile), but designed for Ender 3 S1

You will need for assembly:

• (2) M5x25mm bolt (rollers bracing)
• (2) 608zz or rollers (or just use printable rollers)

Printable:

• (1) spool_shaft.stl
• (2) shaft_nut.stl
• (2) rail.stl
• (2) spacer_5mm.stl
• (1) sensor_holder.stl

Optional:

• (1) addinational_nut.stl (left side retention)
• (2) roller.stl (if you dont have bearing or roller)

Rotation speed of a spool changes due to tightening bolt. Spacer creates friction and stops the spool (or just use printable rollers.stl)
