A stackable rack for storing round or hexagonal containers. It can be adjusted to hold containers of any size. We use it for sample vials (dimensions for 1.5 mL and 4 mL are stated in the scad-file).
If you prefer a design that prints faster and needs less filament, take a look at our Stackable Rack (light version).
Since stl-files are created with OpenSCAD, they often need to be fixed with Netfabb before printing.
This is a pretty basic print. The only things to watch out for are the recesses under the pillars, which usually require supports.
