Arrow keys change the circle into an ellipse. I've now got the drawing loop in a custom block with the refresh off so it runs smoothly. Change the 'r' slider to adjust the radius. Change the #points to adjust the number of points around the circle.
Thanks to @drmcw for help debugging my code. Also, @gtoal. Remixed from @The_Grits for: 3D Pen Cube (Project Remixed) https://scratch.mit.edu/projects/86688842/
