Descrição
This is a reproduction of "The Dana Set of Wooden Crystal Models" originally produced by Dr. Krantz Rheinisches Mineralien-Kontor (Bonn).
triclinic
monoclinic
orthorhombic
hexagonal/trigonal
tetragonal
cubic
I recreated the models based on reference images in "Dana's Textbook of Mineralogy" ([https://archive.org/details/DanasTextbookOfMineralogy](https://archive.org/details/DanasTextbookOfMineralogy)), with forms taken from the catalogue available here (provided by the company): [https://mineralogy.eu/models/Krantz/Krantz_31_3.pdf](https://mineralogy.eu/models/Krantz/Krantz_31_3.pdf)
Whenever a model corresponds to a crystal structure, the known unit cell constants were used. In all other cases I approximated to match the pictures in Dana's book. Please note that I do not have an original set to compare, so there might be small differences. Also the scaling is arbitrary and probably totally different.
Note: Some shapes are identical even though they would be different from a crystallographic point of view, because their faces relate to different axes. I decided to include them anyway for completeness (they are listed in the catalogue so I'm assuming they were actually in the wooden sets), but do consider if you really want to print them twice. It is entirely possible the original models differed in size or axis ratios, which I wouldn't know. This relates to models # 96=97=104, 99=100 & 109=110.
There's a labelled (by catalogue number) and unlabelled version. I also include the OpenScad file I used for embossing, in case somebody wants to adjust the labels.
Changes I made to correct apparent errors in the catalogue (to match Dana's book):
No. 103: {1 0 -1 0} changed to {1 0 -1 1}
No. 138: {2 1 -3 1} changed to {3 -1 -2 1}
No. 145: {2 7 -9 9} changed to {-2 -7 9 9}
Big Thanks to Prof. Gervais Chapuis for making me aware of this set's existence and sending me his catalogue!
