4020 Snap-in Dual Extruder Motor Mount Bracket for Ender-3/PRO
thingiverse
Mounting bracket for dual extruder stepper motors. Unique spring retainers allow this to 'snap' into place on a 4020 v-channel post, which fits just above the power supply on Ender-3/PRO Creality printers. There are also two counter-sunk holes that allow mounting via t-nuts, if the snap-in isn't secure enough for your application - just snip off the spring profiles on the upper half and add your hardware. Probably best to print this in higher-temp plastic (PETG or ABS), but PLA is working fine for me since my ext motors barely get warm. I uploaded a STEP file for easy remixes also!
