ported speaker enclosure

Inspired by youtube videos, I decided to design my own. The main enclosure will take 18 hours printed at 3200mm/minute, each side should be about 2 hours. While you can buy shelf speakers that sound decent, this thing will be louder and kick way more bass. I bought mid-range 3-inch speakers from here:

I'm driving it with one of these amps:

You will need brass inserts and screws for the speaker mounting and closing up the sides:
