Enclosure for RasPi 3 & 2 8 channel relays
Example: Amazon: Elegoo 8 Channel Relay.
Covered with 120mm fan for cooling down with low rpm, so noiseless.
I used this case assembled under my Ikea Lack Table, with Repetier Server and CNCjs on an headless RasPi 3b+ to control three printer and one laser engraver.
The two 8 channel relays controls moreover 2 white led stripes, 1 rgb light stripe, 2 exhaust fans, RasPi cooling fan, 3 printer and the laser engraver, charger for the 10" Tab - which i used to control the raspi.
I didnt find so far, anything like this, so i made my own. I pay the most attention for assembling, so i decided to make it in 3 tiles. If i need an other chassis for a new raspi (change hardware relative often), so i dont must have a full case print
I printed all with 10% infill, 20% would be a bit better.
For assembling you need only four M5 screws and nuts, must check - think it was 45mm screws i used
