Stackable trays! Offered in several variations and sizes! There's a Small, Medium, and Large. Small and Medium will fit on mini-sized printers like the A1 Mini!
I recently (12/19/2023) updated these from the previous version! Fixing some of the printing issues. Additionally, I sized things to be in 3 sizes. Previously I only offered the largest with the suggestion of a .75 or .5 scale. This time I've done it for you!
There's a lot of things like this out there, but these are mine. I originally created them so I could keep screws and misc parts sorted while I built printer kits. Wanted them to be stackable, so at the end of the day I could tidy up my work space. I use them for all sorts of projects now, and they're still just as handy!
