There are two thicknesses and tons of size variations.

We recommend 5x5 for small printers, 9x9 for medium printers, and 14x14 for huge printers.

8mm thicksness is best for most use cases, but you can also print 4mm thick boards to save material

For best results, print flat with default slicer settings.

For extra strength, print with more 'walls' (up to 4 is plenty!).

For light loads and to save material, you can print with 15% lightning infill.
