Sort-Tool Box w/ lock and release function

This is a prototype of my sort-tool box, its a work in progress. let me know if you have any issues

Update: i got recommondations to make the outer walls thicker for more durability. done! the box has now 3mm thick walls and a 2mm thick bottom, including the lower sortbox it makes the bottom 3mm thick. i resized parts to make them fit to the beefed up design

Update: slicer have marked some files as solid. i fixed the meshes with 3d builder and reuploaded every file. issue should be hopefully fixed now
Edit: fixing the meshes, messed with the roundings in the sortboxses, will be fixed soon
