Summary

An altered version of heileh's kubotan, made to be printable by most 3d printers without supports.

Supports added in at the tip because it was still a sharp angle to print at, the flat side doesn't cut down on your ability to hold it much, I find.

I wanted it to be able to print while laying down length-wise because it seemed to me that standing it upright would make the layers more susceptible to being snapped apart.
