Necessary commercial parts
4 stainless steel “608” bearings.
These are the same as the spooler bearings that come with the Prusa MINI.
8 cap screws (M3-15 or M3-16)
8 nuts (M3)
Foam rubber sheet with adhesive on one side.
Recommended thickness: 2mm to 4mm.
Prepare four pieces cut to 16mmx14mm.
Affix these to the bottom of the spooler.
If you omit this, the knob will not function as expected.
Notes on assembly
Each bearing holder has a specific mounting point. Please check the imprint on the printout.
Make sure that the C-ring is inserted in the correct direction. (Please refer to the attached figure.)
When inserting or disassembling the C-ring, be careful not to injure yourself as it may pop vigorously.
Install all bearings first, and then join the left and right frames together.
No rafts and supports are required for this printing.
Print settings
The filling rate should be at least 50%.
Use PETG filament. Clearance adjustment and strength checks were made with PETG.
When freshly printed, the screw may get a little stuck. Therefore, it is recommended to run the screw back and forth several times.
Note
This spooler can accommodate spool with brims up to 140 mm wide.
Spools with an inner dimension of the brim smaller than 74 mm are not available.
