This is a 2U rackmount cage with dedicated modular cases, designed to arrange multiple Raspberry Pi boards like a blade server.

It is intended for use with a 10-inch rack.

• Compatible with Raspberry Pi 2, 3, 4, and 5
• Supports HAT installation (top or bottom)
• Vertical modular case design for each Raspberry Pi
• Power, LAN, and HDMI connections available from top or bottom
• No fixed width, allowing mixed installation of cases with different thicknesses
• Requires M2.5 screws to secure each Raspberry Pi

Perfect for building a Raspberry Pi cluster or homelab in a compact 2U rack format.
Designed for FDM 3D printing 

Many Raspberry Pi rackmount models already exist, but none allowed mixing cases of different thicknesses.
This design was created to solve that problem.
