Jeez! Amazing work. Espacially the kitbash for the vanguard veterans. What kind of left arms did you use? I have seen that the shields are already printed with hands. Did you use the adjustable arms from Popgoesthemonkey.
I bought those adjustable monkey arms and they are complete Fenrisian Wolf excrement. They just didnt have enough of a bend at the elbow to be suitable for holding a shield so I used various marine arm bits i had in my bits box instead. Some required a bit of sanding down to fit but it turned out ok.
Bad news. I ordered those arms as well. The connection to the shields has a strange angle. I tried other arms but it didn't fit very well. First I wanted to use the arms out of the assault intercessor box but those have an extra armor on the sword hand. Let's see how I solve this problem. Thanks for your response.
