Oh man... so using a dremel to cut slots out of HDPE is not only messy but very painful... Not only that, I'm not sure if the entire ensemble would stay together when I put any power behind the motor... so in all honesty, I'm not sure whether or not to bite the bullet and ask if someone could put me together the mechanism in a sturdy metal of some sort... ofc, I'd have to debate on it a little more, but for now... kind of up in the air at the moment. :/
