I use a lot of these wonderful data capture cards from weedtech.com since they are supported by the home automation system of which I am a developer MacHomeAutomation.com unfortunately they dont have good mounting options. in the past I've just hot glued, or cable tied them in place but this is much better. After attaching to this frame I was able to attach them more securely.
Since these have indentations on the bottom for the nuts that hold them in it was necessary to print them with a raft and support. Otherwise I just printed it 100% infill and 1 extra shell.
