FAQ

Are the entered dimensions internal?

Yes. Width, depth and height describe the usable internal area. External dimensions are calculated from the selected wall and bottom thicknesses.

How are the rounded corners calculated?

You select the outer corner radius. The generator automatically reduces that radius on the inside so the wall thickness remains consistent around the corners.

How should the tray be printed?

The STL is exported with the bottom on the print bed and the open side facing upward, normally allowing support-free printing.
