Improved disc

When I printed the original disc, the center was only 1 layer thick with a 0.2mm layer height.
After only a few shots, the plunger that holds down the disks went through the disk completely… (As shown in the photo)

So I decided to beef up the center of the disk slightly in order to increase the longevity of the discs. The center of the discs is now 3 layer thick when printing with 0.2 layers. 

I thickened the center of the disk slightly so that it is 3 layers thick with 0.2 layers to increase longevity of the discs.
