HAND CRAFTED | HAND TESTED

Hand-built mechanical keyboards and over-engineered impact toys — made to order in our Portland workshop.

Evil Engineering

We make seriously enjoyable things you use with your hands by hand in our Portland Oregon workshop.

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 →

Evilly Over-Engineered

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.

QOL Firmware logo with pink 'QOL' and white 'Firmware' on a black background

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.
