This is a cut plan to crate a 10x12 inch round 'crate'. The example was cut in (surprisingly poor quality) 3/8" OSB using an 800x800mm X-carve with a 1/8" bit.

The x-carve Easel drawing is here: http://easel.inventables.com/projects/C9rrlrylnvrGmf2XQ2BV-Q

The source SVG is also included. Load it into your tool of choice and scale it to be 1000x2000mm, using the included squares at those locations. Then remove the squares, set the cutting details, and arrange for efficient cutting. Note that the SVG does include holes in the top and bottom pieces, they just don't show up in the Thingiverse preview. The model is sized for "nominal" 1/2" material. Full dimensional 1/2" material might be a tight fit.
