When I built the Mk2 version last December, I took pictures to document the process. This model is now obsolete, but I think the pictures are still interesting, not only because they show how I built it, but also because they make clear some of the reasons why I decided to change the design. Enjoy!
That’s the Pololu Regulator in the lower right corner
I think it is quite obvious that building the unit is labor intensive. Printing the parts is easy: I used a fine nozzle to print the breadboard (0.25), and the wood-like filament needs a bit of TLC, but there are no supports and it prints mostly on autopilot. The intensive part is preparing the many wires; not that it is difficult, but it takes time. In all, I think with practice I could bring building time to about a day, which is not unreasonable but not ideal either, if I expect to build a system with many modules and would want others to build it, too.
PS. Now that you know how Mk2 was made, you might want to take a look at the Mk3 WIP
