Spool Holder Wall, one part, big rolls (Ex: 2.5kg), 120mm

• Print horizontally (on the flat side)
• 6 Walls / Perimeters 
• Infill: 25% Gyroid
• 0.2mm layer height
   
• Fast printer? Use a “strength” preset or lower the print speed (this improves stability)

The holder supports rolls with a width of up to 120 mm. Filament roll rolls well even without ball bearings (Bambu Lab A1 mini), additional sanding also helps but isn't necessary. I used PETG-CF but all common filaments should work well.
