This is a 4 inch Blastoise pokemon inspired pokeball. i designed this ball myself and is not a copy of anyone elses. The ball is fully functional and can be scaled to 150% larger to be a 6 inch ball. The design does come with a pin to insert between the two halves but I highly recommend using a nail or a metal dowel to go between the ball hinge. I also highly recommend using PETG filament on the inside halves due to how brittle PLA filament is. Its pretty straight forward on assembly, if you have any questions please message me here.
