During today's class, we focused on perfecting the 3D pieces to ensure they fit well together. Our method involved using pliers and sandpaper to meticulously refine each piece while checking the 3d models with Solidworks to ensure how the pieces have to be. 

Sanding process

After completing the sanding process for all components, we double-checked their fit and noticed that the tolerance levels for the wheels and axles weren't quite adequate. We redesigned the axis in Solidworks and print them again so that they fit.

Meticulously measuring the actual pieces for redesigning the parts with the proper tolerances
