Case for RasPi with two 8 Channel Relays

<h1>Custom Case for RasPi 3 & 2 with 8 Channel Relays</h1> <p>For example, you can purchase the Elegoo 8 Channel Relay on Amazon: <a href="https://www.amazon.com/gp/product/B01M61VVGV/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1">Elegoo 8 Channel Relay</a>.</p> This case features a 120mm fan for quiet cooling, operating at low RPM to minimize noise. I built this case under my Ikea Lack Table using Repetier Server and CNCjs on an headless RasPi 3b+ to control three printers and one laser engraver. The two 8 channel relays control additional devices including 2 white LED strips, 1 RGB light strip, 2 exhaust fans, a RasPi cooling fan, 3 printers, the laser engraver, and a charger for my 10" tablet, which I use to remotely control the RasPi. I couldn't find a suitable case like this one, so I decided to create my own. To ensure a secure assembly, I split it into three parts. If I need to upgrade to a new RasPi in the future, I can easily replace just the chassis without having to print an entirely new case. All components were printed with 10% infill; 20% would be even better. For assembly, you will only need four M5 screws and nuts; make sure to check that they are 45mm long.
