This is a contribution to the PolyPanels design competition.
It's a complete concept for solder-free electr(on)ics.
Just take the PolyPanels and two pieces of wire (alternatively two unfolded paperclips).
Insert the wires in the thin holes on the battery holder and in the lightbulb holder, then insert the lightbulb and the battery -- yeah! the light is on.
The design has been made in OpenSCAD. It uses imported PolyPanel snaps from https://www.myminifactory.com/object/3d-print-polypanels-snaps-only-89595
In the coming days and weeks I will add more pieces for other types of batteries and electr(on)ic appliances.
The basic principle will always stay the same -- create electric circuits with very simple everyday items.
The shown lightbulb holder is designed for lamp socket E10 = Miniature Edison Screw.
If your circuit arrangement carries the risk of wires touching each other (= short circuit), you should better use isolated wires and remove the isolation only in the location where contact is explicitly intended.
No need for tools, except for the 3D printer. And - if applicable - a pincer to cut and strip the wires ...
