Azeron Tower Joint Kit in Black. 3D PETG Material for Superior Sturdiness and Resilience. Suits Cyborg ll, Cyborg ll Compact, Cyborg and Cyborg-Compact and Keyzen Models Used in The Left Hand.

Fits perfectly, made by Azeron without the hefty shipping cost. Comes in a five pack (4 identical for the fingers and one for the thumb).

One of the smaller ones threads were useless. I tried pulled out 1 of the metal threads from the old green 1 that originally came with it but could get it out. All the others worked well. Idk about the big one because it hasn't broke yet on the original so I haven't used it yet. I'd give it 5 stars so far if they all worked but I done installed 3 of them and its not worth returning all for just 1 imo. Longevity is still yet to be determined. If it fails quick I'll come back and change my review.
