I got hit with a blast of manic creative energy and thought "hey, could I make a biplane transformer in the style of a G1 micromaster?" I couldn't draw up a blueprint so I had to make a mockup using cardboard and craft foam. With this I was able to make a proper model in tinkercad, which I will share here before releasing it publicly https://www.tinkercad.com/things/egD7SJ9S0c4-biplane-transformer?sharecode=21KcE9hOpnqad8ypB5HXAshXL3seSK_fgJ_i77VZ-Tg
