Ender 3 External Electronics Case with GX12/GX16/XT60 connectors

prusaprinters

<p>This is a remix of a remix. The original file uses GX16 connectors for general wiring, and XT60 for power. The remix uses a DB37 connector (?) for general wiring, and a Auto 6 Pin Power (??) connector for power.</p> <p>This backplate remix uses GX12, GX16, and GX20 connectors, all chosen carefully to avoid mistakes. Also added text identification in sunk relief near them.</p> <ul> <li>4× 4 pins GX12 connectors for each stepper motor (X, Y, Z, and extruder)</li> <li>1× 6 pins GX12 connector for the endstops (X, Y, Z)</li> <li>1× 4 pinx GX16 connector for the fans (overkill, but chosen to avoid confusion with the stepper motors connectors)</li> <li>1× 4 pins GX20 connector for the bed and hotend heaters (the pins of 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 that's overkill for safety reasons)*<strong>EDIT (2019-10-07):</strong> But the standard 24V bed heater for Ender-3/5 has 220W of maximum power, which gives us ≈ 9.2A of current. Too close the maximum specs of the chosen GX20 connector. The thing has been marked as a WIP and will be altered later to include a XT60 connector for the heater bed and another GX12 for the hotend cartridge heater. Better be safe than sorry.*</li> </ul> <p>All those connectors were sourced from Aliexpress: <a href="https://www.aliexpress.com/item/32820896230.html">https://www.aliexpress.com/item/32820896230.html</a> Be careful when wiring the connectors! I didn't add a wiring guide because each system is different, use your common sense when doing that, and check often!</p> <p>I also added the standard LCD plate for the Ender 3; the LCD plate of the Ender 5 is different, it has a tab that doesn't exist on the Ender 3.</p> <p>WARNING: I'm releasing the Backplate file some hours after finishing the design, so it is still untested. The LCD plate is tested and should fit.</p> <p>*<strong>UPDATE (2020-10-26):</strong>* finally finished the addition of the XT60 connector holder for the backplate. Also added a mounting clamp to allow bolting the connector. Both come from this case: <a href="https://www.thingiverse.com/thing:3631413">https://www.thingiverse.com/thing:3631413</a></p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p><strong>Printer:</strong></p> <p>Ender 5</p> <p><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p><strong>Supports:</strong></p> <p>Yes</p> <p><strong>Resolution:</strong></p> <p>0.2mm - 0.24mm</p> <p><strong>Infill:</strong></p> <p>20-60%</p> <h3>How I Designed This</h3> <p>As no-one is adding STEP files for ease of editing, I had to use Windows 10 3D Builder (a surprisingly useful piece of software) to remove the DB cutouts (2 plane cuts to isolate the cutouts, a extrude down to cover them, and a merge to make them one piece again) and Fusion 360 for the rest.</p> Category: 3D Printer Accessories
