Ender 3 External Electronics Case with GX12/GX16/GX20 connectors

thingiverse

This remix builds upon a previous remix. The original design utilized GX16 connectors for general wiring and XT60 for power. This revised version incorporates DB37 connectors for general wiring and Auto 6 Pin Power connectors for power. This backplate remix employs GX12, GX16, and GX20 connectors with deliberate consideration to avoid errors. Additionally, text identification has been added in sunk relief near the connectors. * Four 4-pin GX12 connectors are used for each stepper motor (X, Y, Z, and extruder). * One 6-pin GX12 connector is used for the endstops (X, Y, Z). * One 4-pin GX16 connector is used for the fans (an overabundance of pins to prevent confusion with stepper motor connectors). * One 4-pin GX20 connector is used for the bed and hotend heaters (the pins on this connector are rated for 10A, a typical 40W heater cartridge on a 24V system like the Ender 5 will draw 1.67A max, so it's overkill for safety reasons). However, the standard 24V bed heater for Ender-3/5 has a maximum power of 220W, resulting in an approximate current draw of 9.2A. This is perilously close to the maximum specs of the chosen GX20 connector. The design has been marked as work-in-progress and will be altered later to incorporate a XT60 connector for the heater bed and another GX12 for the hotend cartridge heater. All connectors were sourced from Aliexpress: https://www.aliexpress.com/item/32820896230.html Be cautious when wiring the connectors! A wiring guide was not included, as each system is unique. Use your common sense when doing this and verify frequently! The standard LCD plate for the Ender 3 has been added; however, the LCD plate of the Ender 5 is distinct, featuring a tab that does not exist on the Ender 3. CAUTION: The Backplate file was released shortly after completion, so it remains untested. The LCD plate has been tested and should fit without issue.
