3D printed corners for compartmented box

grabcad

This set of files is designed for 2mm thick walls, but you can adjust the scale to customize this dimension. The main material used is cardboard for the walls; however, other soft materials will work as well. Assembly cohesion relies on ribs embedded within the walls and thus requires a softer material than plastic corner pieces. Removal of top caps may be difficult initially, so sanding is recommended before inserting them. Ensure that any printing stripes are not visible on the spherical end after sanding. To assemble, first cut all walls to desired dimensions and create holes in the bottom wall (40mm diameter for 2mm thickness). Access to a laser cutter can be beneficial; otherwise, use scissors, starting with outer walls followed by inner walls that slightly overlap, and finally the top and bottom. Using an Ultimaker 2 printer takes approximately one hour per corner.
