This upgrade uses wobbleX in the intended way, unlike the version in the WobbleX Git repository and here on Printables.

Simple 1:1 swap with the pre-tension nut V-Minion comes with. Note that this is not a miracle wobbly boi and you will have to have lead screw aligned decently anyway.

You need regular POM TR8x4 nut such as this one https://www.aliexpress.com/item/32920686035.html

You (most likely) need extrusion cap with 608 bearing such as this one https://www.printables.com/model/675495-v-minion-sfs-wobblex-cap

Original Cable holder will fit. It is not in the photos because it would cover everything else.

The lead screw included in RR V-Minion kit it a bit shorter than it could be. You will have to pull it up a bit from the bottom coupler.
