Small storage system, box with hinge

Originally designed as a screw box, I decided it could have many other uses by making different bin and size combinations. I plan to make a stacking system later on plus other bin designs and box variations.
The chamfered top of the bins makes it easy to pick them out and also can be used to put a label on it.

The only assembly needed is to insert a length of 1.75mm filament in the hinge holes to join the top and bottom parts.
The drill bit index works for 3.17mm drill bits, also assembled by using filament as hinge pins.

-Added Bin_SpoolA_38x38.stl, Bin_SpoolB_38x38.stl, Bin_SpoolC_38x38.stl and Bin_SpoolD_38x38.stl which together make a wire spool the size of a 38x38 bin, very handy. You will need to glue the two halves of the spool and the top is attached with two m2x6mm flat head screws.

-By request I added a second version for all the box bottoms with no printing pads also a version without pads for the rack sides Rack_5b5x4_Left_NoPads and Rack_5b5x4_Right_NoPads.
-Added 4b4x3 rack parts to build a rack for four boxes of 4x3 size.
-Added 2x2 box.
-Added 50mm high boxes in three sizes, 2x2, 2x4 and 4x4 plus a few bins for the taller boxes: Bin_38x38T, Bin_38x76T and Bin_76x76T (T for tall).

**Update 19 February 2017**
Replaced 38x38_SlideTop_4Div.stl with a fixed version, the new one comes with its own lid that is not compatible with the other 38x38 bins.
