juryeonggu D14

Idea from [the Internet](https://twitter.com/DorsaAmir/status/1454822232463593472) ([more Background](https://kpopjacketlady.com/2016/12/31/juryeonggu-a-14-sided-die-from-the-golden-age-of-silla/)): A historical Korean 14 side die (about 668 to 935 AD) with drinking game rules inscribed. 6 sides are squares, 8 sides are triangles with the tips cut of. 3D Modelers seem to have a problem with embedding Asian characters. FreeCAD failed to render them at all. Fusion360 produces slightly corrupt STL (Cura complains when slicing - but it prints fine). I'm adding the models (FreeCAD for the D14 version with plain digits, Fusion360 for the juryeonggu variant). Maybe you have more ideas on how to improve it. The model results in a 2cm die. For the final result, I scaled it up to 200% (4cm diameter) and printed it with 50% infill to give it enough weight to feel just right. There are even [math problems](https://www.geogebra.org/m/y8NfENGH) out there on calculating the exact dimensions of the square and the cut triangle sides so they have equal areas and give fair distributions. I just guessed the cut off. But it looks good enough to me. The original game rules seem to be: 1. Sam-jan-il-geo (三盞一去) : Drinking three glasses of liquor at one time 2. Jung-in-ta-bi (衆人打鼻) : Having one’s nose struck by many companions 3. Ja-chang-ja-eum (自唱自飮) : Singing and drinking all on one’s own 4. Eum-jin-dae-so (飮盡大笑) : Finishing an entire cup and laughing loudly 5. Geum-seong-jak-mu (禁聲作舞) : Dancing alone, with no music 6. Yu-beom-gong-gwa (有犯空過) : Staying still without flinching, even when being charged at 7. Nong-myeon-gong-gwa (弄面孔過) : Staying still without flinching, even when one’s face is tickled 8. Gok-bi-jeuk-jin (曲臂則盡) : Finishing an entire cup while interlocking arms with a companion 9. Chu-mul-mak-bang (醜物莫放) : Drinking from a cup without removing something dirty from it (presumably placed there by a companion) 10. Weol-gyeong-il-gok (月鏡一曲) : Singing the song “Weolgyeong” 11. Gong-yeong-si-gwa(空詠詩過) : Reciting a poem 12. Im-eui-cheong-ga (任意請歌) : Asking a companion to sing a song of one’s choice 13. Ja-chang-Goe-rae-man (自唱怪來晩) : Singing the song “Goeraeman” 14. Yang-jan-jeuk-bang (兩盞則放) : When you receive two cups, drain them immediately. (whatever the songs may actually be...)
