David Balfour didn’t like the lack of a mechanical connection for the raduino. So he made a 3D printed frame for the Raduino and uses 12 mm long 3mm screws and nuts to hold it together. It deploys stock front mounts with the original screws replaced by 12mm screws. It sure looks professional. The 3D printer template can be found here:
