Printables is, at time of writing, holding a 3D printed design contest Shape Your Saga: HyperX Mouse. The partner company HyperX tasked participants design parts for their Pulsefire Saga mouse, with emphasis on new top shells for different grip styles. I’ve worked on and off on left handed ergonomic mice and this contest was a great motivation for me to actually finish a design.

HyperX provided models for the shells and buttons as well as a subtraction body. I started by mirroring the side buttons and joining them with a double lever mechanism. The levers connected to the mirrored side buttons were designed to be able to swing 3.2° while the levers that push the circuit board switches were designed for .5° (I assumed 1.5mm travel, like this Omron switch).

I flipped the top shell and attached the front hinges. The rear hinges were made into a separate piece for assembly. The subtraction body was used to ensure clearance for everything. The mouse buttons also needed a bit of trimming on the corners as well and I prettied them up as much as possible using fillets.

Unfortunately, I don’t own a Pulsefire Saga mouse and HyperX haven’t given details on internals so I can’t confirm if this design will work, but if I win a mouse, you can be sure I’ll try it out and iron out any issues. I’ve always wanted a left-handed ergonomic mouse, not because I’m a lefty but because they’re really nice to hold (I have a lefty Logitech MX Master 3S monolith from a postponed project. If I ever have enough disposable income to pull apart a MX Master 3S, I’ll try making a lefty version).

Anyway, after all that, I rendered it and did a sloppy GIMP job to make a catchy thumbnail for my contest entry.

Update: I did not win any prizes
