Edit: 09/14/2015 I've upgraded version C with dual fans, making it a powerhouse for printrbot simples. Edit: 09/10/2015 I've created two new versions - Version B boasts a thicker mouth piece, increased from 2.2mm to 2.6mm and Version C now has elevated side covers along with a thicker mouth piece, enhanced from 2.2mm to 2.6mm. Simply attach this design to your fins and you're good to go! Adjust normals if needed. The gap between the mouths is set at 17mm, and it's a solid 2.2mm thick.
