See whatmouse.xyz for more information - inspired by Optimum Tech's Zeromouse, a sub-20 gram fingertip grip mouse masterpiece, this is my own entry into the Sub20 category.

How much of a difference does a mouse this light make? My 60 gram Logitech G Pro DEX feels penalising after maining this. On a glass pad, a 20 gram mouse delivers a surreal FPS experience: it moves like you're pushing air, and stops with an exactness that needs to be experienced. I've worked diligently on the concave thumb groove, wall angles, and trigger finger divots, to ensure maximum comfort. The feel in the hand is surprisingly ergonomic. 

• PETG recommended as PLA is too fragile for my liking, especially with this print. 
• The holes in the buttons aren't just to reduce weight: they've been designed specifically to optimise the lightness of click, ensuring just the right amount of flexibility. 
• The 6.1 gram chassis exclusively fits the high performance, light weight Razer DeathAdder V3 Pro Wireless PCB. I may create variants to suit other popular mouse internals and you are welcome to remix it yourself.
• When using a DA3 Pro PCB, you will need to de-solder the mouse wheel rotary encoder and switch yourself.
• This is a screwless design: plastic plugs on the base fit tightly into the PCB screw holes, while the rounded-rectangle DA3 laser assembly was modelled and wrapped snugly, turning the whole PCB into a stable platform as a part of the base. 
• 6mm dots are required for mouse skates. I recommend X-Raypad Obsidian instead of standard PTFE, especially if you're using this on a glass pad.
• This mouse is designed to be use on hard pads. Ideally, a glass pads.

Here's the product description, in the spirit of edgy 1990s PlayStation adverts…

Ultra light? Logitech G Pro, eat your heart out. Featherweight? Razer Viper, you're not even close. This is in a league [almost] of its own. You have just a few choices if you want an uncompromisingly exact and unapologetically raw mousing experience. And this is one of them.

 

Welcome to the Sub20 club.
 

60 grams is a relic of the past and precision is now measured in milligrams. In an arena where mousing fidelity separates the champions from the forgotten, there's no room for dead weight. Which is why every gram of unnecessary mass has been stripped away.

 

You think you know lightweight? Think again. This stops on a dime, with zero inertia; with absolute accuracy. This mouse is not about luxury; it's an extension of your will. This is a pure, unadulterated connection to your game. No RGB. No frills. Just you, 19.8 grams of high-performance hardware, and your unbridled skill.
