A Response to Gingerhousing Crisis: overly engineered gingerbread house

It is Christmas time! Declining temperatures and snow is around the corner. Ginger people need a roof over their head! It is time to give them that before they mysteriously disappear again. But unlike last year, this year we aim for precision and engineering, only to be improved next year. We will use 3D design, modeling and printing. We will cast ginger bread walls and bake to be assembled at the construction site. And then we said “Let there be light!”, so I soldered LEDs and powered them with a 5V power supply lying around. And of course with lot’s of “snow” and glitter.

Here is how we did it…

First, we drew the outlines and sketched on a paper. Then I made the models in FreeCAD. Of course when we model something, we model parametric(ally)!

Parametric all the way down

Then we make the pieces as if they are parts of the houseā€¦

Side wall

Then from these models we assemble an house to see how it looks…

Everything was fine, so we moved to make the cutters…

Cutters

So we baked some expired ginger bread dough (bought ready made) with buttered 3D printed cutters…

White parts are the 3D printed cutters and some metal pieces as improvised cable holes
We cheated with some already existing metal cutters, which we could also have printed anyway. The print was too large for my Prusa MK3S so, the corner was printed as a second piece, which snapped into place
So precise

Every house needs “glass” windows. These windows are quite sweet and lemony.

There is no way to sugat coat this but perhaps candy fill

Roof requires some paper support with the snow/cement/glue material (edible).

That’s the hole for the chimney

Then the walls came together with decoration and electrification.

An array of yellow LEDs, an LED strip, a switch and a common energy source.

Some cabling work

Roof, chimney and snow

Ginger person seems to be happy…
