This is a video of the Pen Case model, but the different models work pretty much the same.

Print Instructions and Assembly:

• Print* all parts in PLA, completely and carefully remove support. All parts should fit snugly.
• Use glue to assemble the box (I used universal glue for the bigger parts and super glue for the fragile/small parts). 
• First glue the separate side of the box into the side-part and then glue the two to the rest of the box. Make sure every thing lines up well and that there is no glue in the rails. 
• Weigh down until glue is dry.
• Assemble shutter and end part and align the triangles neatly. Then glue the knob in place. 
• Once the glue on the box is properly dried, you may add a little silicone grease/spray to the rails. It will make the shutter run smoother.
• Put the shutter in. Do this carefully while bending both the shutter and the box just a little bit. At first it might seem that the shutter is stuck and not moving well, but after  opening and closing the box a few times the shutter should run smoothly and should be able to open and close it with just one hand.

*Print Instructions in .stl-File-Names. If you are using the .stl files you need to print the main body in two parts as in pictures (cut it at 3.5mm).

I already printed this a few times and improved it to the point where I think it is working very well. But please let me know if you have problems or suggestions to make it better.
