I am a student interested in building this device as my final year project. I do not have access to a RPT machine and I am afraid that I would not have the time to spend in the woodworking shop to fabricate these parts with dimensional accuracy. I was wondering if someone here would be kind enough to print the RP parts needed and mail them to me. I would compensate you for the material and shipping costs.
getting the parts printed on a commercial machine runs around $1,000. we're working on ways around this. also, i dont have access to a machine. stay tuned and hopefully we'll have some help for you in the near future.
