This is an OpenSCAD file for creating resizeable hinged snap-together boxes. I've printed 3 or 5 so far to hold gifts. Another version I've added cells to to make a box for material samples.

If you want to resize the box, adjust the l, w, h parameters in the OpenSCAD file, and recompile it. Export the STL and load in Makerware.

Resize from inches to mm to display at the proper size.

Print, clear out any supports, and snap together. You may want to file the latch stud down a bit to prevent it from breaking off if using ABS.
