Hexibase Re-Packaged

Inspired by HexiBase, I wanted to make a portable Omni-stereo with preferable packaging dimensions.

Overall size Dia. 225x165mm tall, Coke can in image for size reference.

This is one half of the omni enclosure for the subwoofer; a downward firing, spiraled transmission line.
Transmission line is a approx. 1550mm in length with very similar x-section to Hexibase's.

If you don't have a dual head extruder, the model will have to be split so that supports can be removed.

Design a top enclosure to suit your full range driver and add a reflector. Let me know how you go in the comments.
