A standard lattice cube. Try to test your printer using this model. Scale it up or down as you wish. You can find the original lattice cube solid part that was used to create a Solidworks assembly of 3 cubes. You can add a base part to the assembly as you wish. You can also find the Lib Feat Part of the 5 mm circle used to create the weldment structural member.Please note, I am not the one who innovated this idea of lattice cube. I was inspired by many of lattice cube designs I saw in youtube...
