Scalable Cracker

I wanted to print 4 crackers on a plate at 70%, but they did not scale well... the inner tube was too thick (and I also thought didn't need a lot of the material).
Additionally the "roof" of the inner tube would print badly without supports.

So this version trims the inner tube and makes it a little thinner fixing most of those issues, It can now be layed flat without a roof. I have also printed at 50% for an electronics setup which worked a treat.

Beware yee who scale smaller than 50
