None of these are available in my shop until I get some kreon sets in hand and can confirm the measurements. They are, of course, untested as well.
My first offering is a Simple hand part that allows you to continue to use the legs as fingers, but also includes a thumb joint so that you can attach an extra arm to use as the thumb. It also has a 3mm grip so it can hold onto the weapons.


With the addition of a second thumb joint, these Simple hand parts can double as a small torso

My next set of hands is far more complex but yields greater rewards. These deluxe hands feature 5 individually articulated fingers with 2 joints each and a swivel at the thumb. Rather than relying on ball joints or pop joints, these will require the customer to provide a paperclip to be used as an axle for all of the joints. They also feature a pop hinge joint at the wrist and could easily be adapted for non-kreon customs as they are about Voyager sized. (12mm across the knuckles not including the thumb.



I've gone even further and detailed the Deluxe hands so that there is a unique set for each combiner:
Construction Hands

Combat Hands

Aerial Hands

Predator Hands

Next up, I'm going to work on creating unique helmets for each gestalt and some accessories that will enhance each one.
