Home automation center

WARNING: This is one of my first 3D Designs. The build relies heavily on the PSU size, which can fluctuate, so be prepared to make some post-printing adjustments to assemble the levels according to your printer's accuracy and top cover should be slightly elevated to avoid crushing the Razberry button. Goal: I utilize Domoticz for home automation with the following hardware: - Raspberry Pi 3 (a more modern option, but I can take it anywhere to include new devices) - Z-Wave.me Razberry daughter card - RFX433trx - MySensors Ethernet Gateway - Raspberry UPS on LiPo (not for power failure, but I can take it anywhere to include new devices without the hassle of unplugging and replugging) - Generic 5V/4A power supply (standard adapters are not powerful enough) - SDCard protected, yet still accessible without removal I aimed to create a design that allows me to unplug the server to bring it with me, close to the device to include without halting, unplugging, plugging again, booting, and initializing. I chose a Raspberry 3 for its Wi-Fi chipset and to avoid the need for an Ethernet plug. I opted for a UPS included in the server. I sought a design that isolates high voltage from low voltage components, with separate cells, switchable high voltage input, and a switch for the UPS. I prioritized passive cooling by adding heat sinks to the Raspberry and numerous holes to the case. The hole placement is strategically chosen to maximize natural convection air flow and keep high voltage (heat generator) isolated from low voltage components. I aimed for maximum compactness, keeping the MySensors gateway connected with Ethernet, allowing me to position it optimally for radio communication and connect with the server via Ethernet+Wi-Fi. Regarding the RFX433trx, I chose not to unmount or split the USB power from data, so I kept it as an external add-on. I dislike removing supports from my printings... I wanted a supportless design. The server includes the core (Power supply, UPS, Raspberry, and ZWave shield), with everything else optional (RFX and MySensors).
