This spear head was originally printed for use in the shown Athena cosplay. though printed in Gold, for a more antique look I treated it as described in the post-printing part.

21mm hole fits for 2cm rods.

split in half for ease of printing. also included a vertical split for small printers, which will take longer to print. I did not test this but it should work fine.

added half version without a hole to use as a decoration as seen on the shield in the picture. The "diamonds" around the rim of the shield are also included.
