I completed design on and started 3D printing the cars for our 2021 Speed Circuit season. The cars are inspired by the vehicles raced in the 1971 Formula 1 season including the Brabham BT34, BRM P160, Ferrari 312B2, Lotus 72C, March 711, Matra MS120B, McLaren M19A, Surtees TS9B, Tyrrell.
I designed the cars in Blender v2.83.4, a free program, and sliced them in Cura v4.7. I’m printing the cars on a Creality Ender 3 with a .2mm nozzle set at .08mm layer height. You may find photos of the completed prints in a later article.
