Crank for 1 9/16" Pipe

thingiverse

When we put up the new green screen in our remodeled space at school, there was only one way to store it safely - by taking it off the wall. To make this process easier for everyone, a clever attachment was designed using the open end of the pipe that the screen is currently hanging from. This ingenious solution allows anyone to roll the screen up and down with ease whenever they need to use it. The internal diameter of the pipe where the screen hangs is a precise 1 9/16 inches, which means that the cylinder area was created as close to this measurement as possible in Tinkercad. This innovative attachment was made entirely using Tinkercad's online design tools. Check out the original design at https://www.tinkercad.com/things/afwzUPjCO7u.
