I wanted somewhere to store my hotends that didn't require me opening or digging around to see which one I was after. I also didn;t know how many I would need so I added some friction fit clasps to the design so I couls fix them together as required.
FYI the print on the right was the first itteration, it's missing the notch that lets the hotend sit pleasingly level.
Best to print it upside down to reduce the amount of support material, on the 3mf I've place two back to back so they can share the tree support
