180mm disc for bq 3D scanner

I didnt want to buy an acrylic disc - why not just print it?

This is 3mm thick. Feel free to increase it to by scaling it on the Z-axis.

I printed mine with 15% honeycomb infill and circular solid infill.
I used 3 solid layers at the top and bottom - i recommend using larger since my surface did not cover the honeycomb structure.
