Small stackable crate I've designed. Original size is 150x95 mm, this prints fine with a 0.4mm Nozzle. When scaling down, I would recommend using a smaller one.
Update: By request I've also uploaded the FCStd-file (FreeCAD) but be aware that this is a little bit messy.
Filament brand: Esun, BQ
Filament color: orange, grass green
Filament material: PLA
Most normal filaments print fine without support.
If you want to use more challenging materials (like e.g. wood-PLA) I would recommend adding some custom support for the handles. Infill is pretty much irrelevant, it is basically only needed for printing the top-layers of the floor of the crate. Two perimeters give enough rigidity.
