FabScan Calibration Stand with Plate

This thing is related to the FabScanPi 3d scanner project by Mario Lukas (see https://www.fabscanpi.org). In order to make the scanner work properly, you need to calibrate it with a printed chessboard pattern. For this you need a calibration stand such as the one I made.

It's essentially Marios original holder from https://github.com/mariolukas/FabScan-Case/tree/master/calibration with an additional full plate to hold the calibration sheet. Simply glue the paper sheet directly on the PLA surf
