I am hosting a 3D design and printing contest. I would like to see the product utilized and not just a concept. What should the rules be? Rules: It must be your design and not off thingverse etc. Not just a concept. Show utilization or flight. Post an image with the part, rocket, jig being used. Post the 3d file (STLs can be uploaded). How do I enter? Entering is easy. Make a design in your favorite design software. Open a thread and post images of the printed final products. Add a description of your design and how it works. Post the STL file. Post images of the product being used. What is the prize? This prize is pending. I am awaiting some donations from vendors. Any vendor will get acknowledgment and thanks in the thread. If you want to volunteer a prize, send me a message. So far: - 2 custom 3/8 nylon shock cords from Chute Happens Recovery. - $25 credit and free shipping from Lab Rat Rocketry: www.labratrocketry.com - $25 credit from SMT Designs: https://www.smtdesigns.com/store When is the deadline? 1 October is the deadline. If this contest is successful, I will post one every 90 days. Good luck!
