This thing is a replacment generator for broken or lost assortment shelf boxes. It is fully parametric in size, strength and label size as well as the number of seperators inside the box. There is a demo STL included. The parameters in the SCAD script are commented and self explanatory. You should print with supports for the handle or if you do not care or your printer is realy good at bridges you could try without.

Good luck tinkering!
