Expand – Eurorack modular case system

Ultra-light modular Eurorack case, 3D-printed from durable PLA plastic. Designed to grow or shrink with your setup, this system adapts to your needs. Build your ideal configuration and modify it anytime.

The base cases are available in 63 HP and 66 HP. The 63 HP case can be used with a lid that doubles as a protective cover and angled stand for portability or studio use.
Expandable modules allow configurations from 66 HP up to 70 HP or up to 84 HP, with asymmetric options on each side. You can also combine two base cases — for example, two 66 HP cases — to create a 132 HP wide setup.

2 × 9HP segments expand a 63HP base to 81HP, or a 66HP base to 84HP
