Better switch alignment using a 3D printed jig

A project log for Smaller Simone Giertz's Good Habit Tracker

A PCB with one column per month, each has approximately thirty switches in series and one LED at the end. 367 Switches. Pure Madness.

@sdp8483 wrote in the comments to announce that he had created a 3D printed alignment jig in order to assemble his own Habit Tracker. 

The design holds a column worth of switches and it both pushes the metal case down as well as ensure the separation between columns is fixed.

Here is a picture of his finished Habit Tracker. The switches do look indeed aligned.
