E3D Hermes / Hemera Ender 3 (Pro) mount plate

thingiverse

This is a mounting plate designed to install the E3D Hermes/Hemera direct extruder kit from E3D on an Ender 3 or compatible Ender 3 Pro printer. The model offers cable management facilities and the option to add a bed levelling probe. A BLTouch adapter is available for this mounting plate, courtesy of nimrodxv230. Using an E3D V6 nozzle with this upgrade will result in a loss of 20 mm on the Y axis. To compensate for this loss, you can either program the offset into your firmware or move the Y-axis aluminium profile by 20 mm. This will require you to drill and thread new fixation holes. On my setup, I passed cables to the front of the 3D printer using a custom-made x-limit switch and filament run-out bracket. The posted photographs show a fan duct from James Tongue. Note that I have slightly modified this fan duct mount plate to facilitate its installation. You can download the adjustment at https://www.thingiverse.com/thing:4176741. I am currently running custom-built firmware using an SKR min 1.2 board from Bigtreetech. Check my built configuration on GitHub if you have a similar setup. Update 2020-09-02: Upon request, I added the FreeCAD source file and a step file for anyone using another 3D modelling software. Feel free to remix this design and thank you for sharing any upgrades.
