small parts bins parametric

This is a parametric parts bin design. Using openscad, all dimensions and number of bins are changeable. In addition, I have included a radiused front end that is programmable from zero radius to full wall radius, so that small parts like nuts can be easily taken out.
I provide six stl examples for those who do not use openscad. The largest ones fit on a creality 10s.
Oh, forgot to add. When I made the multi section bins, they can stack. So I had 1 by 1's full depth, and when you do three or more bins per unit, you can go half or one third height and they are stackable.
A final note: you have to set the radius to a value equal to or less than the overall height, otherwise the curved section will go above the wall height. I did not include code to keep the raduis below the wall height.
