Lattice work

I designed this basic lattice work for use on the bottom of my Hypercube (https://www.thingiverse.com/make:332719). It is designed to be flexible so it fits in between the 50mm spacing of the lower rails. In my case I started with this basic shape and then customized a whole bunch of pieces.

In order to customize this piece, which was created originally in 123D, you can convert it back into a solid or just slice up the STL to extend it, etc.
