Ergonomic adapter for choc keycaps to give it some tilt / height so they are easier to press. In the photos I have them installed on my ZSA Voyager. They make the top row of keys easier to press as it brings it closer to my fingers.

This riser allows you to increase the tenting angle of your ZSA Voyager. It's solid and stable, doesn't move as it's tightly secured by the magnet feet of the keyboard. Light weight so you can easily bring it with you on travels. You can add rubber feet to the bottom if your desk surface is slippery.

This connector will let you use your Sawyer Squeeze with any bottle that uses a 28mm thread (like a smart water bottle). I use it as a gravity water filter system when backpacking. Connecting the clean water bottle to the filter makes it easier to setup the gravity system as I don't have to worry about the water not dripping into the bottle.
