Arduino PCB Standoff mount
by AKAMEDIASYSTEM, published
This mount gives you a few ways to securely connect boards, shields, and peripherals. Prints fast!
The shape is simple and easy to modify in Sketchup. I made this to attach a Sharp IR sensor to an arduino+ethernet shield stack.
The holes are 1/8 inch diameter, and I've been gently tapping each hole with a machine screw before installation...no problems so far!
This will fail miserably if you use the default settings on a Makerbot :-(
I had much better results when I selected the "High" quality setting in MakerWare (I'm using PLA on a Replicator Dual here at work).
Want to modify it? I included a Sketchup file as well. You might want, for example, to replace the vertical holes (which make connections to the Arduino and a shield) with little nubbins that stick up, so that the stacking action of the shield holds the block in place...
