In this post I describe two Python <\/a>programs that I wrote to create nice compartment layouts for my parts boxes.<\/p>\n\n\n\n Both generate OpenSCAD programs, but also directly usable This repository<\/a> contains two scripts that take the puzzle work out of your hands:<\/p>\n\n\n\n boxGenerator.py creates a free layout of rectangular compartments within a box.<\/p>\n\n\n\n You specify:<\/p>\n\n\n\n The script tries to place those compartments within the available surface.<\/p>\n\n\n\n The program works via an interactive prompt.<\/p>\n\n\n\n The script tries to place all compartments. If that fails, it indicates:<\/p>\n\n\n\n Here you can see how this works in practice:<\/p>\n\n\n\n And below is the result:<\/p>\n\n\n\n gridLayoutGenerator.py works with a fixed grid.<\/p>\n\n\n\n Inspired by Gridfinity<\/a>, but without the overhead and therefore using less filament.<\/p>\n\n\n\n Everything is based on a grid size. All compartments are multiples of that.<\/p>\n\n\n\n This provides:<\/p>\n\n\n\n Three working modes<\/p>\n\n\n\n The program produces two output formats:<\/p>\n\n\n\n The program works via an interactive prompt.<\/p>\n\n\n\n The prompt looks like this:<\/p>\n\n\n\n .. and this is the result:<\/p>\n\n\n\n If you want you can leave a reply.<\/a><\/p>\n\n\n\n 111 keer bekeken \/ views Dividing a drawer seems simple\u2026 until you want to combine multiple compartment sizes.
