This is a keychain spinner with built-in bearing, and print-in place for easy setup for everyone (print without supports). I printed it out of PETG, and I used Prusa MK4 printer, but I believe most printers should not have problem with printing, just watch out for tolerances (there are tolerances already in the model, but they are tight).
I hope no one will have problem printing it, and I wish you fun playing with your new keychain spinner!
