Ender 3 Sonoff & RPi Power Supply

thingiverse

This creation aims to maximize the potential of the Ender 3, OctoPI, and Sonoff Basic. Why I Created This: I designed this for my brother, who also acquired an Ender 3 shortly after I did, and sought a single power cable that could extend down to the wall outlet or power bar while using a Raspberry Pi for Octoprint. Key Features: * Auto-on and auto-off capabilities for the Ender 3 when printing jobs are spooled * Utilizes Tasmota-MQTT and MQTT plugins in OctoPrint with a Sonoff Basic to achieve this Required Components: * 12V DC switch from AliExpress (https://bit.ly/2Gu5LlK) * PC Power cord from PricessAuto (https://bit.ly/2MhKgbB), in addition to the one included with the Ender 3 * AC Input block from AliExpress (my prototype used one from a broken ATX Power Supply) (https://bit.ly/2Kaplo7) * Two 6mm grommets from AliExpress (https://bit.ly/2yjJQcd) Design Improvements: * Universal tray design for circuit boards, allowing easy replacement and modification * Wire management holes through the walls for required connectivity Assembly Instructions: 1. Remove endcap to access Vslot rail insert for installation behind LCD display 2. Slide case into position, aligning power cord with Ender 3 Power Supply 3. Test and validate RPI power supply before assembly Future Updates: * v3.0 STL files include wire management holes through walls * Trays will be uploaded once completed, modified for specific circuit boards
