This model was designed to house three 22mm buttons to control the power to my DIY CNC machine.  It can easily be expanded to any number of buttons.  It has tabs with 3mm holes for mounting to a surface or aluminum extrusion.

The top is secured to the body via 2x 3mm flat head bolts and heatset inserts.

A hole for the connecting wire must be drilled through the body.  This is not included in the model to allow for variability of location and gauge of wire.

The printed model was made of out Apollo X ASA - Grey with a 0.6mm nozzle.
