E3D Hermes / Hemera Ender 3 (Pro) mount plate

thingiverse

This is a mounting plate to install the [E3D Hermes / Hemera direct extruder kit](https://e3d-online.com/e3d-hemera-175-kit) from E3D on the Ender 3 or compatible Ender 3 Pro printer. This model features some cable management facilities and an option to add a bed levelling probe. A [BLTouch adapter](https://www.thingiverse.com/thing:4194573) is available for this mounting plate, courtesy of [nimrodxv230](https://www.thingiverse.com/thing:4194573). Using an E3D V6 nozzle you will loose 20 mm on the Y axis with this upgrade. You will have to either add this offset on your firmware or, if you want to recover these 20 mm, you could move the Y-axis aluminium profile by 20 mm. This will require from you to drill and thread in new fixation holes. On my setup I passed the cables to the front of the 3D printer using a custom made [x-limit switch and filament run-out bracket](https://www.thingiverse.com/thing:3743586). On the posted photographs you can see a [fan duct](https://www.thingiverse.com/thing:4042492) from [James Tongue](https://www.thingiverse.com/Hangtight/about). Note that I have slightly modified this fan duct mount plate in order to facilitate this installation. You can download the adjustment at https://www.thingiverse.com/thing:4176741. Currently I am custom built firmware using **SKR min 1.2** board from [Bigtreetech](http://www.bigtree-tech.com/). You can check my built configuration on [GitHub](https://github.com/franpoli/Marlin/tree/Ender3pro-Hemera-SKRminiV1.2-BLT-FilamentRunout) if you have a similar setup. Update 2020-09-02: Upon request I have added the FreeCAD source file and also a step file for anyone using another 3D modelling software. Feel free to remix this design and thank you for sharing any upgrade.
