Boxer Flat Four Reduced Size

I initially want to print the original, but it was too big for my Printrbot, so I decided to cut it in half, by having in one half the left head and the crankcase and the other half the right head .
I also cut a lot on the sides .
For the pistons, crank and the rods you should take them from the original .
I also made some holes in order to connect the 2 sides by zip ties, and also keep the crank in place .
I only printed the bottom half, then put the pistons and crank and it's pretty nice to rotate the crank and see how the pistons move like a Boxer's hands !
It would be nice to make a bigger design and somehow connect the crank to some little electric motor .
