Every keyboard ships with my QoL firmware — a custom VIAL fork with autocorrect (including a curated 3,667-word dictionary), autoshift, and smart defaults all enabled from the moment you plug in. No setup needed, no configurator deep-dive required. Want to customize? Everything's fully open through VIAL, and source is on GitHub. A QR code in every package links you to firmware updates, the VIAL configurator, and a quick-start guide.
Evil Engineering
Hi, I'm Delilah. I make over-engineered impact toys and mechanical keyboards in materials most 3D printers won't touch — polycarbonate, carbon-fiber nylon, glass-filled ABS. The same stuff that makes riot shields, drone frames, and cockpit windows. Every piece is made to order, guaranteed for the life of my business. Read the full story →

Rigorously Tested
Evil-Engineering makes over-engineered impact toys from aerospace-grade thermoplastics. Every design is printed in-house on enclosed, high-temperature industrial printers using materials like polycarbonate, carbon fiber nylon, and glass fiber reinforced ABS — the same classes of material found in ballistic shields, aircraft components, and industrial machinery.
These aren't hobby prints in PLA. They're functional tools built to perform, with layer orientation, wall thickness, joint geometry, and material selection all driven by the specific mechanical demands of each component.

Our Materials: PETG
PETG is our accessibility-tier material — easy to print, widely available, and offering a solid balance of toughness and flexibility. It's the material that makes our "lite" product line possible....
Read moreOur Materials: ABS-GF (Glass Fiber Reinforced ABS)
Glass fiber reinforcement increases ABS's stiffness and dimensional stability while reducing warping during printing. The result is a material that holds tight tolerances and resists deformation under sustained load. Keyboard...
Read moreOur Materials: ABS
ABS is one of the most widely understood engineering plastics, and for good reason. It's stiff, reasonably tough, prints reliably in our enclosed heated chambers, and — critically for certain...
