This is a very old model I created in 2015 and imported from my Thingyverse profile (https://www.thingiverse.com/TheZerschmetterling). Maybe some links are broken or not up to date. If you have any questions do not hesistate to ask.
Motor mounts designed for the FireFlo v2 and FireFlo v3 Frame.
They are available in 6, 7 and 8.5mm.
Have fun.
