Kobalt mini toolbox pinning kit
This is designed to fit into the top of a Kobalt mini toolbox. It's a pinning kit basedd off the Lab mini kit. There are no markings on it and it could be used for many other things as well. You have two options. The first one is printing in 2 pieces. That version should fit on most printers. Option 2 is printing as one piece. That's the better option but many printers don't have a big enough bed. There are spaces to place magnets that will help hold the lid closed.
The optional magnets for holding the lid in place are 8 millimeter in diameter and 2 millimeters thick.
