To keep some essential tools close to the printer and having a small trash can ready to dispose small filament bits quickly I created this backpack or quiver style container, that hooks up to the outside of my 3d printer. - This will work universally for any printer with a wall thickness thinner than 5mm.
0,3mm or as fine as you like
The walls are 1,5mm thick, so use a setting that will create solid walls out of them.
With 0,3mm layer height I used 4 shells to create solid walls while building up the container. - No support is needed, but cooling is recommended since the bottom will be bridged in the printing process.
