This is the first version of the breadboard holders I am satisfied with showing, as all of my past attempts have needed tweaking and improvement to get it to where it is today. This development began before I started designing the enclosure, and I will include any photos I have of prints I have leading up to the first version of the model.
The modules link together horizontally, and then slot into the enclosure vertically so there isn’t a need to worry about them coming apart while you are working.
Currently the pieces lack the ability to be very easily removed, as I intentionally make the tolerances tight enough to avoid rattling when the device is in transit. This is the last thing I think I need to work on regarding these holders.
