Chisel Protector - customizable and easy to print

Lots of these on Thinigverse but I wanted one that was customizable and easy to print without supports. Just change the nunmbers in the vector at the top to select which sizes you want. Remove lines if you only want to print 1/2 at once.

I can upload specific sizes for people if you don't want to learn how to drive OpenSCAD.

Sizes in stl are 6mm, 12mm, 18mm and 24mm as below (with clearance added.)

// Vector of widths and heights
// Generate one at once or all together, you choose.
Tools = [
[6.45, 4.9],
[12.4, 4.7],
[18.4, 4.82],
[25.4, 5.4]
