Adafruit Swirly Aluminum Mounting Grid for 0.1" Spaced PCBs

With most of our dev boards, sensors and feathers now sporting plug-and-play stemma QT ports it can be very fast to put together projects with half a dozen boards snapped together. But that ease of use has one downside: now you don't have a breadboard as a mechanical substrate... which is why we created this nifty swirly grid design to allow for easy mounting of various small microcontroller and sensor boards.
