Ender 3 left side spool holder (extended and strengthened)

thingiverse

I designed a robust holder for heavy filament rolls by modifying this design. The sides of the holes are now reversed so they remain hidden from view when looking at the printer's front side. Additionally, the height has been increased to 28 mm, up from its original 20 mm dimension. Furthermore, I thickened the area surrounding the screw holes for added strength. To print it, I used PLA material with a layer height of 0.2 mm and a width of 0.4 mm. The structure features four layers of wall support and seven layers on top and bottom. I also utilized a 20% gyroid infill pattern and provided internal supports within the screw holes to ensure stability during printing.
