20mm Thin wall hollow cube. No support PLA

thingiverse

Create a hollow cube with a 1.2mm wall and devoid of internal support; print quality is optimal on a Printrbot Jr using PLA filament and a 0.4mm nozzle, with layer heights set at 0.3mm and extrusion temperature at 200°C. No cooling is necessary during the printing process, as fan pressure may hinder layer adhesion and result in brittleness. Print results exhibited no sagging but featured a slightly rough top surface, as demonstrated in high-resolution images.
