Description
The chassis uses as little filament as possible
The spool can be placed above the machine (like mine in my photos) or below; it works very well.
I used 3D-printed ball bearings from https://www.printables.com/model/33110-bearings-library-airsoft-bbs
You need to use the bearing model with an inner diameter of 18 and an outer diameter of 35.
