Arc Pro B70 OCuLink Bench Bracket - NFHK/OpenClaw

### Intel Arc Pro B70 OCuLink Test Bench Bracket — NFHK Adapter (OpenClaw Themed)

A 3D-printed GPU support bracket designed for open-bench testing of the **Intel Arc Pro B70** connected via **OCuLink** using the **NFHK 4X OCuLink SFF-8612/8611 to PCIe x16 Adapter**.

**⚠️ Compatibility Note:** This bracket was designed specifically for the NFHK adapter linked below. Other OCuLink-to-PCIe adapters have different mounting hole positions and board dimensions — they probably won't fit.

### What It Does

- Supports the Arc Pro B70 in an open-bench / test-bench configuration

- Mounts to the NFHK OCuLink adapter board

- Provides stable GPU positioning without a case or chassis

- Features OpenClaw branding (open-source agentic AI platform)

### My Build

This bracket is part of a compact AI development workstation I built using a mini PC with an OCuLink port, the Intel Arc Pro B70, and llama.cpp running local LLM inference via Intel's SYCL/Level-Zero backend.

The full build story and benchmarks will be available soon.

### Print Settings

- **Material:** Overture PETG

- **Slicer:** Bambu Studio — generic PETG filament profile, generic print settings

- **Supports:** None

- **Tweaks:** None — I was planning to dial it in but didn't have to. It printed clean on the first try.

- **Print Time:** ~1.5 hours

That's it. No special tuning. If you've got a Bambu printer and PETG loaded, you can slice and print this without touching a single setting.
