very nice... I looked at the pics and didn't read cause i have homework but my sugestion if you haven't already, put the filter as a CD drive peice that way you can just slide it out replace it and slide it back in... you may have done this if so sry.... also you should make the little handle on the top removible for adding food (if you haven't already) Looks very nice and clean! Thanks for the post!
