The spool holder is designed for spools with hole sizes ranging from 25 to 70 mm using a 608 bearing.
Instructions:
- You need to drill out or clean up the thin boundary above the bearing after printing.
- A spacer should be added between the bearing and the holder to prevent binding.
- Note that the hole for the bearing is a tight fit (22mm), and you may need to enlarge the diameter slightly depending on your printer's calibration.
- You can use a clip instead of a nut for quicker spool changes. The top side of the clip (as printed) should face the bearing.
