A case for a barebones component tester can be made. https://www.aliexpress.com/item/Free-tracking-DIY-kits-Mega328-LCD-Transistor-Tester-Digital-Combo-Diode-Triode-capacitor-inductance-resistor-SCR/32746416115.html This project requires the following components: 4x M3x30mm bolts (any head type will do) 4x M3 square nuts The design works well with these settings: PLA material, 0.4mm nozzle, 0.2mm layers, 1.2mm wall and top thickness, and 20% triangles infill Specify 0.4mm external perimeters in Slic3r Supports are only needed for the top surface to hold up the inset area in one corner. No support is required in the rounded corners of each part's circumference. Avoid placing supports in the door slide area or square nut recesses. Note that the nut recesses can be "skinned over" with a single layer, eliminating the need for support. A drill bit and blade can clean up any rough spots. The door may seem tight, but it needs to fit snugly. Even a slight rough surface finish on its final layer or some debris in the two slots it slides through may cause issues.
