ben 10 omnitrix 13 accessory

this is a ben 10 omnitrix dummy 13 accessory. I used the forearm piece and it should assemble pretty easy. I modeled it in tinkercad. if you want it bigger just upscale it it should work i think. and for the carbon 13 just click it on and upscale of you want i made both type m and f. Happy printing!
