Mechanical 7 segment display with tighter CAM tolerences

The original model was not tight enouth for me when using a precise printer.

Made those changes:

• Made the SEG_PLATEpin for CAM 1mm taller. This make the cam jumping out of place les likely.
• Made the SYNC_GEAR hole smaller to have less play between the SYNC_GEAR and the SEG_PlATE. You can adjust it via the variable “syncGear_hole_thickness” in the fusion 360 model. Default diameter is at 8,1mm.
•  Made the CAM_D1 and CAM_D2 hole smaller to have less play between the CAMs and the SEG_PlATE. You can adjust it via the variable “cam_hole_thickness” in the fusion 360 model. Default diameter is at 6mm.
• Made the CAM_D1 and CAM_D2 square bigger to have less play between the D cams and the A, B and C CAMs. You can adjust it via the variable “cam_square_thickness” in the fusion 360 model. Default diameter is at 0,15mm thicker than the original.
