Jinbao Devastator knee adapter.Designed to connect the V1 leg upgrades to the V2 leg upgrades.Add extra height and proportions to you Jinbao Devy by combining the two leg upgrades without having to cut existing parts.
Fits my Jinbao devy and upgrade kits, though please be aware that as 3rd party addons, the existing upgrades may vary fractionally.
UPDATE: Included a second stl. This is a slightly revised version with a little cropped off the mushroom peg that attaches to the V1 leg extension. Now the small, spring latch can completely close and ensures a better fit.
