This is my very first model, I design fun simple prints in my free time. I love Star Wars, Marvel and BattleBots. This is a mini model of my favorite bot from BattleBots, Tombstone! (2019 version) The beater bar on the front spins kind of like a fidget spinner and the wheels spin as well. The wheels themselves are Lego pieces none of which are rare or hard to find. Here are the piece numbers: 2x 18978a (the rims) 2x 72206 (the wheels) 2x 3749 (pins) 1x 4211815 (axle) 2x 59443 (connector) (photo above). You will need 2 Wheel hubs, 2 End caps, and 2 washers. The assembly is very simple, for the weapon just put the weapon bar in the hole of the bottom weapon holder, then slide a washer on then the beater bar then the second washer then put the top weapon holder on top. finally glue the end caps on the top and bottom. For the non weapon parts, glue the the top weapon holder (which should be attached to the weapon) to the main chassis and glue the wheel hubs around the hole made for the Lego parts and voila! I hope you guys enjoy this model! Btw no supports are needed and I printed this with a Sovol SV06 but that wasn't an option for some reason.
