# Skeleton Mouse Designs Kotinos Uses an Open-Frame Shape Tailored to Individual Finger Placement By Amy Duong | Published 2026-06-17 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/kotinos References: [yankodesign](https://www.yankodesign.com/2026/06/15/exoskeleton-mouse-gives-each-individual-finger-its-own-ergonomic-saddle/)  The Kotinos is an experimental [wireless mouse](https://www.trendhunter.com/trends/air-nova) created by psudoku that replaces the traditional mouse shell with a lightweight [3D-printed framework](https://www.trendhunter.com/trends/exoskyn). Instead of supporting the entire hand, the design uses individual fingertip pads mounted on a skeletal structure, allowing the palm to remain suspended above the device. Built around donor components from the HSK Pro mouse, the project is fully customizable through OpenSCAD scripts, enabling users to adjust dimensions and finger positions to suit their own hand size. The open-frame construction exposes the mouse’s internal electronics, including the circuit board, scroll wheel assembly, wiring, and sensors. Available as a free open-source project, Kotinos can be fabricated using consumer 3D-printing methods and assembled with salvaged hardware. The design explores an alternative approach to [ergonomic input devices](https://www.trendhunter.com/trends/ergonomic-computer-mouse) by reducing hand contact to a few strategically placed points rather than relying on a full palm-supporting shell.
