#3DPNSpeakerCover Air Driven Spinning Cover

This spinning speaker cover is designed to fit the sub H1456-08 ER18RNX made by Seas. The spinning feature is built like a fan blade and should spin just from air being pushed out by the sub!

To print: Split into separate parts (there are 3), use supports on build plate only. Soluble interface obviously will give you a better surface finish but it can be printed without it. Any layer height .2 or less will work. Since this has a large diameter, if you know the material you're printing has a tendency to shrink, increase the scale by 1-3% to compensate. It is VERY important that the hub has clearance to the fan. To be on the safe side you can print the fan larger by a few percentage points, although if your printer is well dialed in, then it might be too loose. Infill 15%. Make sure ensure top layer thickness is checked to prevent gaps as both the fan shroud and fan itself have very shallow horizontal slopes.

I love product design and really enjoy 3D printing as a manufacturing method. Most of my designs & prints end up as rewards or teaching aids in an elementary school. I also run a small Etsy shop, https://www.etsy.com/shop/BooleanCustomDesigns.
