  * 8x sinkings for the vitonballs in each panel:

  * We measured the diameter of the glasballs and saw an inaccuracy of **80mm +/- 20müm**. Therefore we put the balls in a 5.Xmm test-hole and measured the ball-high in different position with the CNC-maschine:

  * After the "ball-high-measurement", we calculated the mean value and drilled again test-holes, for example "Kugel 1" **5.Xmm + 19.4müm**, and measured again. We saw a really nice result! After a 1cm test-milling and a good result, we milled in the mounting-breadboard:

  * We build everthing together and measured the high of the mounting on different places with a provisional result of **+/- ~80müm**:
