Drop + biip MT3 Operator Keycap Set

For our latest MT3 keycap set, we simply let a legendary designer operate—and operate he did. Meet the Drop + biip MT3 Operator Keycap Set: a modern, lighthearted marvel of design fit for any Mech Keys setup. The mind behind fan-favorite sets like Extended 2048, Dots, and more, biip has a knack for memorable keycap creations—and Operator is no exception. Inspired by industrial product design with a focus on functionality, this subdued-yet-striking set sports clean, modernist lines with a rounded font and iconography. Ultra-readable, the handcrafted legends can be found in pairs on many of the keycaps, doing double-duty that reduces the overall Base Kit count by working with a wider range of builds. This utilitarian advantage is one half of the naming inspiration—the other half comes from the colors. A primary retro grayscale keeps things both old-school and orderly (perfect for MT3 profile), while accent colors sport a neutral tone with a functional purpose: to delineate upper rows, additional layers, and functions. It’s a subtle presentation, but the appeal comes through loud and clear. Your next keycap set is just a call away: dial Operator. 

Our first-ever exclusive profile, MT3 is a reimagining of retro typing experience—with a look and feel that’s made for the modern user. Designed in collaboration with Matt3o, it’s based on the original beamspring terminals from the 1970s and heavily sculpted: meaning the contour from row to row forms a concave shape, designed to minimize finger travel. Each MT3 keycap also sports a scooped top: a nod back to beamspring terminals, with a slightly refined shape to better fit today’s boards. Made from durable PBT with dye-sublimated legends, keycaps in the MT3 Operator Keycap Set are built for the haul—not just the long call.  

A big name in the world of Mech Keys, biip is a designer that doesn’t miss. Active in the community for over 5 years, he’s had more than a few big hits: Milkshake, Extended 2048,  Twist, and Dots among them. Based in Strasbourg, France, biip began his career as a graphic designer upon taking an interest in visual arts from a young age and later studying applied arts. After becoming Art Director at his agency and spending over a decade in the communication world, biip decided to devote himself full-time to designing keycaps sets, while also providing digital design services. This move was well-earned: his sets are bestsellers here on Drop and beyond—MT3 Operator is just the latest in a successful operation.
