Korg Delay Monotron Analogue Ribbon Synthesizer with Custom 3-D Printed Keyboard

via this auction

"Includes a 3D printed attachment which makes the Korg Monotron's ribbon keyboard much easier to play by adding tactile keys. It fits all three Monotron models: Original, Duo, and Delay. This attachment allows for greater precision and reduces the time needed to competently play a melody. Also, it helps train your fingers to make Monotrons easier to play without the attachment. After using this tool for months you'll never want to play a Monotron without it."
