Stepper motor pulley puller Ender 3

cults3d

This puller is strong enough to do the job, just remember to make it 100% full and position it horizontally so that the wire is the full length. I still had to use a workshop press to unlock the pulley on a third engine, so it will be a bit of luck... After a few returns from people who had their extractor broken at the base, I took back the extractor version 2 and I made 2 holes to insert the screwdriver and the allen key (supplied with the Ender 3) to consolidate it even more.
