CalDigit TS3 + Dual SSD Front Modular Rack System
Print Profile(1)
Description
This module adds front-access I/O and storage expansion to the modular 3U rack system, designed specifically around the CalDigit TS3 to integrate seamlessly with the Mac Studio mounts and other system components.
It combines a secure TS3 dock mount, dual front-access 2.5" SSD bays, and a high-speed USB4 extension, transforming your rack into a clean, accessible workstation hub.
🧩 What This Module Does
- Mounts a CalDigit TS3 dock securely inside the rack
- Adds two front-access 2.5" SSD slots
- Extends a high-speed USB4 / Thunderbolt port to the front
- Keeps cables clean and routed internally
- Maintains full compatibility with the modular rack ecosystem
This is ideal if you want your rack to feel less like storage and more like a desk-integrated workstation.

🧵 Print Recommendations
Materials:
- PLA → will work
- PETG → recommended
- ABS / ASA → best (strength + heat resistance)
Notes:
- Use reinforced bolt hole profiles
- Avoid low infill near mounting points
- Internal component mounts benefit from higher wall count
⚠️ Design Notes
- SSDs are designed for tool-less slide-in access
- USB4 extension routing is internal, ensure cable bend radius is respected
- CalDigit dock fit is based on standard dimensions, verify if using alternate models
- This module prioritizes clean front access over hot-swap speed
🧱 Modular System Compatible
Works with:
- Mac Studio left/right mounts
- Blank plates
- Future expansion modules
Mix and match to build your ideal layout.
💡 Why This Exists
Most rack setups hide everything in the back.
This flips that idea bringing storage, high-speed I/O, and daily-use ports to the front where you actually need them.
