This is a remix of the spool holder coming from creality wiki, but in this case, it's fixed on 2 sides of the upright. I think it will be sturdier.
Printed with "Quality" profile, using support and infill density at 25%. It takes around 92 gr of material... from my side I used PETG.
The 2 additional screws are M3x12.
New version v2... Same base as the previous version but having a support for the Nebula camera and also a filament guide.
A lot of fun with this new version :-)
