I made these frames easily stackable both in the same size and sizing down as you can see.  I do need to hit them with a sander real quick to smooth them off. It is a side affect of faster printing or lower resolution, but just as a sizing guide this works well to produce them quickly in hours instead of days. Realistically once all the bucks are printed we can have vacuum formed sizing guides. I am doing this first to determine how far down I need to go down.
