To use, arrange storage bins on a baseplate and put the tray on top. Dump items on the tray and slide them into the appropriate bin.
Tested the 4x6 version, prints fine with standard settings.
Parametric model: you mainly need to edit ‘nx’ and ‘ny’. There's a bug where the filet disappears when ‘nx’ is changed, see screenshots: just edit the filet, select the edge of the hole and apply a 2.5mm filet (or whatever up to about 3.5mm), then the model should be OK again and all holes have a filet. ‘nx’ must be at least 2, ny at least 3.
The author marked this model as their own original creation.
