About this 3D model
Remixed Solidude's vertical plate mount to allow for extruders other than the stock SeeMeCNC EZ/EZR units, and added support for a second extruder while I was at it. This will let you use a Titan, BMG, or other mount-to-NEMA17 type extruder unit. I've had good luck with the Winsinn dual gear units on 0.9 degree stepper motors. Haven't tested it yet. Please let me know if any issues. Original idea found here: https://www.thingiverse.com/thing:2313574
