These speakers are a customized version of http://www.thingiverse.com/thing:451253, created using customizer, http://www.thingiverse.com/apps/customizer/run?thing_id=451253. All credit goes to Rich Olson who built this - http://www.nothinglabs.com/speakergen-parametric-3d-printed-speaker-enclosures/ It was printed on the Monoprice Select Mini using Hatchbox Wood filament at 215 extruder/55 bed temperature. I used a raft but no supports. The mini was able to handle printing the roof of the box without them, so ymmv on that. I ordered the drivers and terminals from parts-express.

I finished them using two coats of minwax stain and two coats of polyurethane.
