Koeksister cookie cutter

My very first upload, hoping someone somewhere will use it.
Koeksister is a proudly South African confectionary.
Wife asked me to print a koeksister cutter because the dog got hold of her commercially bought one and they are fairly expensive.
I tried to make the "blades" as thin and sharp as I can without losing strength and stability.
I've included a 50mm cutter and a 90mm cutter. Handles are separate and must be glued onto the body with some Superglue or such.
