Simple multipeg storage bracket to mount your smaller weight plates also called change plates in one place instead of all over the bloody floor. The main unit stores 4 peg, and depending on your printer you can divide it up in slicer to multiple parts. Uses screws or lag bolts to mount. I also have a extension peg available if you want to go that way or add some more pegs to the bracket. I seriously suggest using filament like HIPS with a .8mm nozzle for these.
