Car body for excavator print on prusa

STL- In order to increase mobility, recent excavators are often equipped with wheels to run on the road, but in the past, many were manufactured with tracks to suit the uneven construction environment. There are still excavators made with track, but these excavators have the disadvantage of being carried by trucks. Still, I think the track is the representative method of excavators. So I designed a car body that can replace the mobile lower body with a track type. STL- Build 2 types of excavators with these parts! Which excavator do you like? 1: 48 Scale
