MRU (Multiboard Rack Unit) is a community remix project by RetroDuck89 that enables 3D-printed rack enclosures using the Multiboard ecosystem. MRU introduces custom parts only where necessary to bridge Multiboard-native builds with standard rack-mounted equipment.

Part Overview This part is a 4 MRU (4U) MRU T-Series Rack Rail, provided as a left/right pair.

MRU T-Rails combine:

• standard rack spacing (EIA-310 compatible)
• on-grid Multiboard mounting and threading

This allows a single rail system to support:

• off-the-shelf rack equipment
• 3D-printed shelves and panels
• native Multiboard tiles and accessories

⚠️ This is an early (v0.x-beta) release intended for experimentation, testing, and community feedback.
