Basic Air Track Glider

This is a basic model for an air-track glider. The idea is that the regular metal gliders are so expensive, yet they would be so easy to make with a 3D printer. This will hopefully help lower the cost of successful physics education, while also opening doors for customization.

I will be making prototypes and adjusting the model, but I would also like feedback from you out there (especially physics teachers and students) on how to make this a more viable product. The data I need is specificall
