Creality Ender 3 BMG Direct adapter for the stock carriage

thingiverse

The adapter allows you to mount the BMG extruder directly on the original carriage of the Ender v3 (Pro) printer. I recommend using the pancake stepper motor instead of the original nema 17 due to the significant weight reduction. The forces on the small motor will be sufficient because the BMG extruder has a 3:1 reduction gear. The use of pancake motor required me to reduce the currents on the windings (in Merlin settings) to avoid strong heating. Suggestion - I did not think about it when I made one piece for myself - it is good to make a hole for a cable tie or design (feel free to remix) a hook for a cables harness. For me they look ugly and probably wear out slowly... I am attaching the model made in FreeCAD v0.20 + ASM3 WB. It probably contains some specific features of realthunder LinkDaily branch, so in the upstream version it may throw up model errors.
