This is a mount for the Drakon geared extruder, inspired by the Speed Drive mount (https://www.thingiverse.com/thing:3816051).
My goal was to reduce the weight of my direct drive setup by using a smaller stepper motor in combination with a geared extruder.
Fitted with a 20mm deep pancake stepper the whole assembly barely clears the left extrusion of the z-axis, so no need to relocate the x-axis endstop and no loss of print area.
The whole setup is roughly 40% lighter than before.
I printed this face side down with supports and 20% gyroid infill.
For installation you need to fit the sleeves of the x-carriage wheels into the 8mm holes in the mount. You probably need to heat them with a soldering iron similar as you would do with threaded inserts.
Edit: I've added a x-axis endstop mount that you can bolt to the x-axis directly with a M4x8 hexhead bolt and a M4 t-nut.
