lithophane base x files

lithophane base. If you change some things, it could use with any lithophane
To make the lithophanes: http://3dp.rocks/lithophane/
the size of the original picture is 780x400 px, and I used this configuration to make them:
Maximum Size (MM) 150
Thickness (MM) 3
Border (MM) 0
Thinnest Layer (MM) 0.4 (because my nozzle has the same size, if you use a 0.3 nozzle you should set it at 0.3 or 0.6)
Vectors Per Pixel 4
Base/Stand Depth 0
Curve 0
I've add the model with neither letters nor space to the switch in order to modify depending on your needs
