This is for the ender 3 / ender 3 pro

(mine is direct drive so it looks different but it should be fine on normal ender 3s)

print instructions:

Cog A is printed with supports with a blocker in the mounting point

Cog B is easy just lay it flat on the build plate

infill: negligible anywhere between %5-100 

Assembly instructions:

superglue the cog in the divots in Cog A  and then your done :)
