About this generator
Cardboard and refill spools often have a different hole size than your holder. Print one adapter per side of the spool.
How to use
- Measure the spool's center hole.
- Measure your holder's rod (or use the 608 bearing option).
- Print two: one for each side.
Printing tips
- Print with the flange down.
- A bearing makes the spool turn much more smoothly.

Frequently asked questions
What should I measure?
The diameter of the hole in the spool, and the diameter of the rod on your spool holder.
Why use a bearing?
With a 608 bearing in the hub the spool turns much more smoothly. The rod then goes through the bearing (8 mm).
