4AVA ModuLes

Created for Ava by Uncle Les, these 4AVA ModuLes are a work in progress. Please do not print at this time unless you are willing to experiment as they do not properly interlock yet. They will, however, become a unique and useful Lego-like interlocking toy, building block, and maker resource in time.

The blocks are arranged in a 3D checkerboard fashion that is denoted by code as "if (x+y+z%2) block();", or in other words just add up the sum of the integer positions of x, y, and z, then take the modulo 2 of that sum. If the result is one, put a block there and if not, leave it empty. This makes a 3D space filling checkerboard, neat huh?

So far so good, however there is a problem. We need to make the blocks be exactly the same size as the empty space between them to get a nice firm interlock. This means subtract the nozzle diameter from the block size, arrange them into a brick as described by the modulus of sum above, and we're good to go right?

Unfortunately if we just do
