3d printed an oblique pen, resulting in the worst caligraphy you ever laid eyes upon:
Being a lefty with a weird pen-holding style, an oblique holder is necessary to actually write with a dip pen instead of digging for China. That it works at all is interesting. Suddenly I can tell what it's supposed to be doing and what I've been doing wrong.
I did not design the oblique pen, Manticorp did and Theremar remixed it to fit more pen nibs.

Oh, and the recipe I use for my ink now:
16 parts Prussian Blue suspension
2 parts DOT-3 brake fluid (I kid you not)
1 part water
