Geeetech A20M direct dual-drive extruder mount
Description
I haven't found direct dual-drive extruder mount for geeetech a20m so I designed one. It fits with standard a20m screws and doesn't block second bowden tube so changing colours works just fine. Should work with A10M too. You'll need to calibrate retraction settings, but 4mm 30mm/s doesn't seem to string too much. Also I would recommend using dual Z (like this one: https://www.thingiverse.com/thing:4049225 ) to prevent x axis sagging on the right side due to significantly greater mass of the hotend
