This little helper holds your scissor upright, so you can use it with only one hand. I designed it in three parts: the platform, a clamp, and a screw. As a special ed teacher, we use this with kids with cerebral palsy in the art class, for example. You can buy these as well, but they cost around 50€. As we need a lot of them in school, it is way cheaper to print them. Maybe you know someone who'll find this thing as useful as I do. Please check out my website as well: http://makershelpcare.de
I made one video to explain it and one where I designed it both are in German and you'll find them below. Enjoy!
