This modular rack system is designed for users who need a flexible, sturdy, and clean housing for their networking gear, lab equipment, or home server components. By combining 3D printed vertical segments with standard 2020 aluminum extrusions, you can build a rack tailored to your specific depth and width requirements.
Key Features
Infinite Scalability: Add "Middle" segments to increase the height in 1U increments.
Easy Printing: All parts are designed to be printed easily without any supports, saving you material and post-processing time.
Sturdy Design: Uses 2020 aluminum profiles for the depth, ensuring the frame won't sag or twist.
Standard Hardware: Designed for M6 screws and nuts, which are widely available and provide excellent clamping force.
Flexible Width: Use aluminum profiles for the width to make it a standard 10" rack, or define the width using the rack panels themselves.
The 3 Printed Components
The system consists of only three unique parts:
End Piece (1U + 20mm): Includes mounting point for the 2020 profile.
Mirrored End Piece (1U + 20mm): A mirrored version.
Middle Segment (1U): Use as many of these as needed to reach your desired U-height.
Note: The end pieces are extended by 20mm to accommodate the 2020 aluminum profile thickness.
Required Hardware (BOM)
Aluminum Profiles: 4x 2020 Extrusions (Length depends on your desired rack depth).
Screws: M6 x 12mm (For connecting printed parts and mounting to profiles).
Nuts: Standard M6 Nuts.
(Optional): 2020 profiles for the width if you prefer a rigid frame without panels installed.

Assembly Tips
Sandwich the Middle Segments between the Top and Bottom end pieces.
Secure the vertical assembly to the 2020 aluminum profiles.
If building a "floating width" rack, ensure your equipment panels are sturdy enough to maintain the rack's geometry.
