Scad Pentominoes

First upload! Look for more Scad as I learn.

This puzzle was presented by [numberphile](https://www.youtube.com/watch?v=wZ1E_CM7MqA) on YouTube. I looked for one here and found a few, but none in Scad. This is perfect for Scad.
So I fixed that.

[Here is a link](https://isomerdesign.com/Pentomino/) that looks at problems to solve with these puzzle pieces.

**WARNING!** These pieces fit together perfectly. For me. I recommend printing out the test shapes to see how they fit together before committing to the whole thing. I've included stl's for printing out two test shapes, and another to print all but the test shapes.

You could shrink the cubes, but then you have to join them. Making the gaps bigger is not a simple exercise. I may take that on if I get complaints.

The image is a 17 hour print at 0.3mm x 0.06mm in transparent orange PLA. I didn't test it first and man did I luck out. Sometimes you win.
