This is a cover for the FG085 Digital Function Generator (e.g., as found on Sparkfun KIT-11394 and elsewhere). Since this product has a front face and rear face (but sides are exposed), this 'thingi' case is in two halves which snap on to complete the shell. Holes allow access to power and usb plugs. Heat ventilation holes are positioned just above the back-lit LCD display.


Print each part separately, top down on the printer platform.
I used medium, with 3 shells and 0.2 layer thickness on Makerbot 2.

For the top part, the vent holes above the LCD display are a challenge. Besides greatly increasing print time, these prove to be a "torture test" for the printer. If you have a problem with the circle outlines not sticking to the platform, you might prefer the top without the vent holes. (See photos.)

The size and shape of the function generator has changed. I printed this cover and it did not fit the width or depth of the generator I put together. Also the generator I received has a small apex on the sides that now has to be designed in. Thanks for the ideas, I am just modifying your basic design to make a cover for my unit.

I had the same problem, as well as not knowing how to seal the "seam" on the edge, so I made this http://www.thingiverse.com/thing:688659

FG085 Slide On Enclosure

Oh, awesome. I was staring at mine just a few days ago thinking I needed to enclose it. I wasn't even looking for one here, I just figured I'd CAD it up. But now, I'll just do yours instead! Thanks!

Great to hear. I hope it works well for you. Upload a picture when you print it. If you improve on the design, upload that, too!

Done! That was easy! Shared 3D design FTW!
