40mm Fan Grill - Curves

I wanted some fan grills to put onto my new 3D printer (http://bit.ly/1mBe9Mo) to keep the stepper motors a bit cooler when I enclose all the electronics.

This fan grill is designed to fit into a hole in a 3mm ABS (or similar) sheet. The actual 12V DC fan will then sit on the other side of that.

Mounting holes are 4mm in diameter and 32mm apart which seems to be the standard for most fans.

Let me know if you print it as I'm still waiting to get an extruder for my printer.
