Scotty suggested a double sided raw pcb and to cut holes into it where the future modules will be placed.
Since I did not have such a pcb in my stock but was fortunate enough to find some brass profiles I used these to build my frame.
I cut them to size using the following template on Scotty's website and hardsoldered them.
Unfortunately they get pretty messed up during the soldering process.
To clean them up you have to bath them in a 40% sulfuric acid solution and wipe them clean afterwards using a polishing cloth.
The last step is to drill mounting holes into the frame's edges.
