Inspired by classic BBS wheels on racing Porsches. This version has spokes instead of a smooth face. Has an axle built in so it can be easily mounted on wheels. Compatible with Medium Lego Technic Racing Wheels (56x34mm). This wheel model has been updated to change the axle size for a better fit. It has been printed successfully; pictures coming soon. IMPORTANT UPDATE: I received my first version in the mail. Its axles were a bit big, so this version has had them resized to fit better.
