LEGO : modeled & 3D printed

I modeled some legos beams with Fusion 360 to understand the standard dimensions.
Then I designed some swap parts which don't exist at the lego list to print them and complete my building set.
The idea was to create a "Mad Max Claw car". For this purpose i needed new rims style, an off road tyre and new wings shapes to match the muscle car shape. I added some holes on the top of the wings too to add some spikes.
The images show my 3d models, but i suceed to 3d print them too and all my new parts perfectly fit with the official parts.
