For this project, you’ll need:
- Around 80g of PETG, printed at 0.2mm, 10% infill, and 2 shells
- Around 50g of TPU, printed only with shells at 0.2mm
- 6mmx100mm steel rod
- 2 x 626 bearing (6x19x6mm)

The design is made so all parts can be printed without any support.
The PETG parts can be printed all at once with that specific parts placement:

Here’s the final product!

Print your own spool holder and give it a spin!
Happy printing!
