Let your imagination run wild stacking squares. With essentially an infinite number of choices in the customizer you can be assured no one will have an object just like your's. By changing the dimensions you can make planters, trays, bud vases, pencil holders, bracelets, or drinking glasses. The simpler smaller objects make good demonstration pieces and will print quite quickly.
Update: Moved max layers from 200 to 800. Careful with the higher layers it could result in long renders. Also added a control to force the design to be hollow if you can't do it in your slicer.
