This model can be used for 1kg filament spools.
I used PLA in the colors black matt and red.

For better long-term use, I implemented a short piece of PTFE tubing to guide the filament.

In addition to the 3D printed parts, four 608 ball bearings are required.

(outer Diameter: 22mm, inner Diameter: 8mm, Thickness: 7mm)

The model is designed so that no support material is needed and all parts fit well.

I added my Bambu-Slicer-Model in the Data description (Filament dispenser BabmuSclier).

I used a .2mm Layer-Height with 15% Infill and ironed all top surfaces for a nice look.
