[Update] There is now also a stackable tray, labeled versions for all boxes and a half-height version of the smallest box that can stack 2
This is a small parts tray with a large variation of boxes. The tray is designed to have the max size on a Prusa MK3s print bed when using a brim.
Tray size: 24cm x 19.5 cm. This means your print bed needs to be at least 24.5 x 20 cm large.
There are a variety of boxes included. The naming for the boxes assumes that the width of the half-tray (left/right side of the central barrier) is equal to 1.
So 8 different base sizes with one in 2 height versions. Please refer to the illustrations for the different options.
Print the tray with a brim to ensure the corners don't lift off. Otherwise nothing special needed. Instead of a brim, - if you want to save some filament - add cylinders of size 10mm x 10mm x 0.2mm high ("mouse ears”) to the corner of the tray/boxes in Prusa Slicer. The long sides of the tray do not need a brim.
