Parameteric Stacking/Sliding Drawer Boxes
by holgero, published
This is inspired by http://www.thingiverse.com/thing:34534 , but I did the scad files myself (I wanted to have the stuff parametric...).
Stacking of these does not really work and printing the rail thing in upright positon was a dumb idea in hindsight. But it is good enough to store some LEDs for now, so I am putting it to use and perhaps you'll find it usefull too.

Adapt the size paramters to your needs (size[XYZ] describe the size of one drawer) and check if the grip is still rendered correctly (the grip might not be 100% parametric, I tweaked it so it worked for the two drawer sizes I printed.) Perhaps increase the "wiggle" parameter a bit, I had to make use of a file to get the drawer run smoothly in its rails (see the debris in the picture).
Then render to stl (or use the uploaded stl files if the size fits your needs). Edit the last else branch to render one of the rail, lid and stacker modules. You can set alltogether to true to see everything rendered together and the drawers inserted in the rail thing. (Note: I had to increase the number "Turn off rendering at " to 100000 to get it rendered as CSG).
I sliced at a layer height of 0.4 mm with slic3r and printed it in ABS. The rail thingy is printed with support, but that was maybe a bad idea, cleaning the support was a tad difficult. Also it split on the horizontal lines because there was too much warping. Perhaps slicing with a smaller layer height works better...
Print one of Triple Rail, 3 Stakers and a Lid.
Getting the Lid to stay on the Stacker or the Triple Rail does not work very well, I think I will give up on the stackable part in the next design.
