Description

This is a reproduction of wood models originally produced by Dr. Krantz Rheinisches Mineralien-Kontor (Bonn). I tried to recreate the models based on the catalogue available here (provided by the company): https://mineralogy.eu/models/Krantz/Krantz_models_12.pdf

Some notes: Only the face indices are given in the catalogue. Angles (where not anyway constrained by symmetry) and distances from center are missing, and I don't have a set of original models available to compare. I tried my best to come up with printable models which could correspond to real crystals, and they do fulfill the symmetry, but most likely the originals look at least somewhat different.

There's a labelled (face indices and catalogue number) and unlabelled version. I also include the OpenScad file I used for embossing, in case somebody wants to adjust the labels.

Print Settings

Printer:

Biqu B1

Rafts:

Supports:

Yes

Resolution:

0.2mm

Infill:

10%

Filament: Fillamentum PLA Pearl Night Blue

Notes:

I advise printing cubic-holohedral-3 with supports (build plate only), because this part has a small contact surface and severe overhangs on the lower faces. Everything else can remain supportless.
