I wanted to make my own version that is freely available for anyone to use and customize for their Miku cosplay
The main size of these is 80x80mm OD, ~70x70mm ID and 18mm thick. If a different size is desired, scale everything to maintain tolerances.
Print 2 of everything with the inserts red and the rest black. Slide the insert over the main piece, then slide the top onto the main piece and insert. I would glue them together for stability. My plan is to JB-weld a barrette style hair clip to the inner wall of the main pieces to affix to the wig.
EDIT: For the usual cosplay wigs for Miku that come in three parts (base and 2 twin tails) scale this to 1.25x scale. It fits perfectly over the hair clips at a 45 degree angle and stays in place without any fastener
Printed mine with Overture Black and Fresh Red PLA.
