This is just a simple switch panel I made for my boat. Most boats have these items installed so I got these waterproof switches from amazon.com http://www.amazon.com/gp/product/B00RZ4WEIA/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 This panel is 4 mm thick and I filled it 10% with a standard wall it seems plenty strong and the switches snap in perfectly. Or if you have other switches you can resize the holes ofc. The words file is just to designate the items I intend the switches to activate but b/c they are a separate file you can ofc change, rearrange, or delete them all together and still print the panel.

I have a dual extruder printer so I opened the base file and positioned it on my build platform. Then I opened the word file and elevated it by 4mm above the build platform b/c thats the height of the base piece. Then I positioned it accordingly relative to the switches. That way I could print in two colors. You can combine this however you like.

I printed it with a 10% fill with a standard boarder it seems plenty strong. Enjoy.
