Model of my Lynx velomobile.

thingiverse

To scale down this velomobile model to any size you want, use basic arithmetic operations. For instance, if you want a 1:12 scale, you would reduce it to 8.33%. I suggest arranging the components as shown in the Simplify 3D screenshot for optimal results. To print the body, start with one side at a time and assemble the parts together afterwards for a better outcome.
