HyperX Pulsefire Saga - ergonomic design

I present my model, born from the combination of simplicity, ergonomics, and innovative design. The idea sprang immediately to mind upon seeing the contest, and I dedicated time and numerous modeling trials, using various filaments (PLA, PETG, and TPU), to achieve the desired result.

The ergonomic design allows for a comfortable grip, enabling both the thumb and pinky finger to rest on two side wings. This solution promotes a smooth and frictionless mouse movement.

A distinctive element is the integrated TPU wrist rest. Instead of using a pre-existing model, I designed a modular solution to ensure comfort and ease of printing. The wrist rest consists of a rigid PETG base that connects perfectly to the TPU cushion via centering cylinders.

Aware of the inconvenience of constantly repositioning the wrist rest, I integrated it with the mouse using an adjustable joint secured with a simple 10mm M3 screw. This system keeps it always within reach and allows for easy adjustment of its position to the size of the hand and movements.

To optimize printing, the mouse body is designed to be printed slightly inclined, improving layer adhesion and strength. The wrist rest, on the other hand, is designed for vertical printing with a flat base, reducing the need for supports to just the centering cylinders and ensuring a better finish and greater robustness.

As illustrated in the GIF, assembling the joint to the base is intuitive: simply insert the joint into the slot and lock it with the pressure cylinder, which clicks into two internal concavities, preventing the joint from coming out of its housing while maintaining freedom of movement.

For printing, I recommend the elasticity of PETG and, ideally, a matte finish to improve grip.

• Filament: PETG
• Walls: 2
• Top and Bottom Layers: 3
• Infill: 5% or 10%
• Infill Pattern: Adaptive Cubic

As for the TPU cushion, I recommend these settings.

• Filament: TUP
• Walls: 2
• Top and Bottom Layers: 2
• Infill: 5%
• Infill Pattern: Gyroid

This project is the result of time and passion, as demonstrated by the various tests conducted to achieve the final outcome.

I hope you like my work, and I look forward to seeing your print combining colors and perhaps other materials.

Happy printing.
