Ender 3 Dual Z Kit Bearing Spacer
thingiverse
The Ender 3 Pro BLV dual Z upgrade kit (https://www.aliexpress.com/item/4000424565743.html) seems to come with missing parts (only 1 spacer for e.g). To remedy this, I designed a replacement spacer. NOTE that the seller has now achknowledged the issues and has included an extra spacer in the kit. They've also included 2 extra bolts (separate issue). Even with the additional hardware, I still feel that the right lead screw needs an extra 3rd spacer and a locking collar to stop any vertical movement. I've since moved to a 2 stepper configuration.
