I designed this enclosure to house and cool 5-8 stepper drivers controlled by a single Uno! to drive my MPCNC with ESTLcam Firmware, but still retain full power capability of my 2 amp nema 17s.
The way this is accomplished is with the help of a second cloned cnc shield v3.
The enclosure is made by 8 5x3mm round neodymium magnets I glued them in with ca glue.
The hinge pins are 1.75mm filament that I use a lighter to melt the ends to enlarge them.
