Gravity45 is a 40% layout mechanical keyboard with a separate left/right structure that was launched on August 27, 2025.

It was a hot topic, with several media outlets picking up on the story.

Mr. d./// will be selling an original case that he designed exclusively for Gravity45.
One major feature is the three-piece design (top case, middle case, and bottom case).




It uses a floating structure with MoutPin, and is characterized by a relatively soft key feel.

Since it is not equipped with forms, etc., the keyboard has a relatively clacky typing sound, making it a keyboard that is fun to type on.

The products are handmade in limited quantities, so those interested should visit the booth as soon as possible.
