Begin by studying the "Assembly.stl" Sketchup 8 file.
Next, print parts. All parts were printed using Makerware "Standard" settings:
1) Print 1 each of "Base.stl", "Back.stl", "Font.stl" and "Top.stl".
2) Print 2 each of "Side.stl" and "Pin Hinge.stl".
Finally, assemble parts (make sure you study "Assembly.skp" for proper position and orientation):
1) Place "Front.stl" on a flat surface, then press one "Side.stl" on one end of "Front.stl", and press the second "Side.stl" on the other end. I found a rubber mallet made it easier to press the sides onto the front.
2) Press "Back.stl" on the two sides. Again, a rubber mallet helps here.
3) Press the assembly just made into "Base.stl". Some sanding, filing and/or trimming may be necessary to fully seat the assembly in the base. If you are planning to put something heavy in the box, a small dot of cyanoacrylate in each corner of the recess in "Base.stl" may be necessary.
4) Position "Top.stl" on the assembly between the hinge assemblies on "Back.stl", then insert the two "Pin Hinge.stl" pins. After insertion of the pins, if the top does not pivot smoothly, remove the pins and top, then, using a hand held electric drill, run a 3/16" drill bit in REVERSE through the hinge pin holes on "Top.stl" (running the drill in reverse avoids "bit grabbing" which could potentially break the hinge off of "Top.stl").
5) Enjoy. I would like to see the color combinations you choose.
