3D model description

I use electrical outlet junction boxes quite often as project cases when dealing with AC. It's easy to find low profile single gang boxes, but not so much triple gang boxes. I whipped this up tonight in SketchUp (yes, people do successfully use SketchUp for 3d print modeling) after a trip to my local hardware store left me empty handed. I only needed the 3-gang version, but the other two were easy enough to extract so...

For my particular need, I only needed mounting holes in the bottom of the box and I needed one particular hole for the AC in line. This is a simple enough design. Using the CAD program of your choice, you can add mounting tabs or holes to suit your needs. Or, if you go with 100% infill, just drill holes as needed.

I am a self-proclaimed know-it-all. I will tackle any project regardless of my experience, or lack thereof. Always ready to learn something new. With over 25+ years experience in electronic repair and 10+ years experience in small engine / ATV / motorcycle repair, there is nothing I can't fix, modify or build.

Why a pepper? In case anyone is curious as to why there is a hot pepper embossed into most of my designs... My nickname is Pepper and that little pepper logo is a hell of a lot shorter than "Copyright © 2017 by Derek J.G. Tombrello" which is how I usually sign my work :)
