These are designed to be two part replacements for the hat switches on the Logitech/Saitek X56. Print the stem in transparent PETG with a raft transmit the RGB lighting better than stock. Then print the caps in TPU and press fit them on. If you play in VR, you should use all three, or if you play on a monitor, mix and match as you see fit. They are smaller diameter than the stock hats, so they allow better access to the A button with your thumb.
