Basic parametric snap fit electronics enclosure / box. Printable without supports.

You can size as you like using user parameters in Fusion 360. F3D file supplied. When exporting STL / STEP, it will already be orientated ready for printing.

I've kept it as basic as possible so you can further add your own customisations to your project.

The example STL supplied is to have same internal dimensions as a UB5 Jiffy Box.

Photos show my PETG print from a BambuLab P1S with a 0.4mm nozzle, at 0.24mm layer height and 0.6mm line width (150% nozzle diameter) for quicker printing.
