Holy Dagger of Antioch (handle sold separately)

thingiverse

This started as a calculations exercise, to stretch a cube along its diagonal. I like the idea of putting appliques on polyhedral facets. Hence was born the "Holy Dagger of Antioch," (handle sold separately).... Not to be confused with the Holy grenade of Antioch or any British movie actors purporting to carry said blade..., There are 5 scad files here, one for a base, two for a cross applique, one off angle for better 3D printing and a tilted ring, and one with a cross of David applique. The fourth file is for the cross of David applique only. To accommodate the stretching process, the raised areas of each applique must be tilted slightly upward. Lines for partial tilting and scaling in the cross of David program are commented out and replaced by "non-stretch" presentations. But not all the tilting stuff was implemented in that final version (too tedious :o ). With the conventional cross, it was only necessary to raise the z-axis for the middle coordinate of the cross, easy peasy... It did turn out grand, and if I ever get some golden shiny filament, I may try to actually print the cross of David version. So enjoy, it's fun to see what's possible with a little trigonometry on a cold winter's day. Also a personal note, some micro-fiddling with corners of each structure was needed to seal the 3D surface without holes (i.e. to compile the scad file). FYI: A little trial and error usually fixed that problem :) To orient a cube for vertical stretching, take inverse sine of 1/(cube root of 3)
