Remixed Left Case

This is yet another remix of the excellent Teaching Tech Ender 3 all-in-one electronics left case. The changes for this case include a different DC-DC converter and relay module from the ones used in the original design. The DC-DC converter is a DZS Elec model number Super LM2596S, 9 – 36 V input, 5.2 V output up to 6 A (depending on input voltage). The DC-DC converter has both a USB-A connector and a wire output. I used a USB-A to USB-C right angle (both ends) cable to provide power to the Raspberry Pi 4B. I used the wire connectors to power a 5 V Nocturna NF-A4x20 fan. The choice of parts allowed me to put this together without soldering, although connecting to the relay might have been easier if the wires had been tinned.

The DC-DC converter fits into a well and is not attached to the case. The reason for this is that it allows the converter to be removed (without disconnecting any wires) to provide access to the micro SD slot of the Raspberry Pi. Access is not easy, but I have b
