Dragon Breather Plate for printer enclosure

thingiverse

This is a muffler Plate with a cool Dragon (found on grabcad) for reducing the sound of my 3D printer enclosure. The design seems to work well, but I'm still unsure if it breathes enough - after all, I'm not running ABS or anything. The new design now breathes through the middle of the part instead of the bottom and uses a Polygon pattern because thin unconnected walls weren't sticking to my bed. Additionally, I decided to bolt it to the enclosure from the inside so there are no counter bores showing on the part. Unfortunately, the meshmixer supports didn't work out well for me - they seemed to break off during print and caused some stringing as a result. The bed supports near the center where the polygon is smallest probably aren't necessary, so I'll remove those when I get a chance and beef up the horn supports instead.
