Raspberry PI Case for Ender 3v2 PSU Control
thingiverse
A Raspberry Pi enclosure for Ender 3 v2 that has room for mounting 2 x buck converters and 2 x relays for PSU control/LED lighting control. Intended to be mounted out of the way on the right rear rail with 3mm t-nuts. Buck converters are the commonly available "adjustable" type. Eg, https://www.aliexpress.com/item/33004374185.html Relays are less common optocoupled design that run from 5v but work with the extremely fussy Raspberry PI GPIOs as well as being "high" triggered. Eg, https://www.aliexpress.com/item/1005001619535486.html Two versions of the base are included, one with all standoffs and one with just the PI standoffs. The later is probably more useful as variances in mounting holes for buck/relays mean these likely should be customised to suit.
