Irregular wheel demonstration model

Interchangeable parts that you can put on a case I made with a pin to hold the irregular wheels and demonstrate how different shaped wheels need differently shaped roads to roll smoothly on. In this case case we will say smooth rolling is when the axel on the wheel stay on the same height level when rolling across the road. !IMPORTANT! The first print plate contains all necessary parts and all the plates after are the individual parts in case your printer messes up!Boost MeI would love a boost and its free :)
