Dummy 13 - Improved Kasa Hat Accessory

Based on a design by Colorado Science. I found the original a little difficult to print and a bit loose fitting. Redesigned from the ground up.

Reshaped the slot (using the official hat accessory as a base) to better fit the dummy's head, and adjusted the model so that the brim of the hat prints flat on the build plate, limiting the need for supports. Other than that all dimensions are the same or similar to the original. 3mf file set up for fuzzy skin with a modifier to prevent the inner walls being printed fuzzy to maintain a good fit. Overall it should print easier and fit better.
