Here is a pair of add-on parts for Transformers Combiner Wars Sky Lynx (Sky Reign) and Dezarus (Leokaiser). The parts add some much needed bulk to the legs of these combiners. There is a 5 MM port on the side to give you the option to store items on the thigh.
This is sold as a set of 2 pieces connected together. You will need to separate them and cut off the excess plastic
To install you will need to transform the thigh so the bottom of Sky Lynx's feet are facing forward. The parts will peg into the bottom of the feet.
This is intended for adult figure collectors. This is not designed for rough play by children.
This was printed and tested on my home 3D printer with PLA plastic. Depending on the plastic you choose, sanding or polish may be needed to fine tune the fit.
