How about a pay per 3d file option?

I am a teacher and do not have a budget to support $99 per month. What about a pay per download option?
I have a model of our school that I want my students to print and then design an expansion of.

Any thoughts?

Thank you for your feedback. Though we do not offer a pay per download option at this time, we do offer pricing for educational institutions. To learn more, please contact sales@dronedeploy.com.
