Doorknob helper customized (Corona)

I reached out to the creator on Facebook about customizing their innovative project. Check out this amazing hands-free door opener: https://www.materialise.com/en/hands-free-door-opener. I had three ideas for modifying it to suit our school's needs: * Printing without support * Reducing the number of parts (no nuts needed) * Changing the diameter (clamping prism) * Making it faster to print I hope I'm not infringing on their copyright by sharing this. If so, I'll delete it right away. After some experimentation, I achieved a clamping force of 30 N using two 1.5-liter bottles attached to the longest lever arm of the handle (7 cm). That seems like a good starting point. If you decide to customize or publish this project, please give credit where it's due: https://www.materialise.com/en/hands-free-door-opener
