Enclosure Extension with Magnetic Mesh Integration
Budget: $30 – $250 USD
======================================================================
PROJECT DESIGN BRIEF: 50MM CHASSIS EXTENSION WITH MAGNETIC INTEGRATION
======================================================================
----------------------------------------------------------------------
1. BASE FILE REFERENCE (ONSHAPE PUBLIC DOCUMENTS)
----------------------------------------------------------------------
- Repository Search Query: Minisforum DEG2 eGPU Enclosure V2.0
- Public Document Creator: Dopins
- Target Format for Modification: STEP File
----------------------------------------------------------------------
2. PROJECT OBJECTIVE
----------------------------------------------------------------------
Modify the public community .step file referenced above to accommodate a larger, high-performance graphics card. The total enclosure length must be cleanly extended by exactly 50mm.
----------------------------------------------------------------------
3. CRITICAL HARDWARE ANCHOR (MINISFORUM DEG2 DOCK)
----------------------------------------------------------------------
- Hardware Constraints: This printed enclosure acts as a form-fitting shell over a physical Minisforum DEG2 eGPU dock.
- Protected Zones: All factory mounting screw holes, alignment tabs, rear I/O cutouts (Thunderbolt 5, OCuLink, LAN, USB ports), and ATX/SFX power supply connector channels MUST remain completely locked in their original spatial coordinates.
- Execution: Execute the 50mm extension strictly on the forward overhang section of the chassis frame. The rear mounting footprint must remain 100% untouched to ensure the shell still mounts to the dock hardware perfectly.
----------------------------------------------------------------------
4. CAD WORKSPACE ALIGNMENT WARNING
----------------------------------------------------------------------
- Coordinate Discrepancy: The internal global coordinate system in this specific base public file is inverted/misaligned relative to standard orientation.
- Alignment Rule: When the case sits upright on its physical feet, the global 'Front Plane' behaves as the bottom panel and the global 'Top Plane' behaves as the physical front face.
- Instruction: Execute the 50mm geometric extrusion strictly along the global 'Top Plane' directional vector to ensure the enclosure elongates straight forward without twisting, warping, or distorting the side ventilation patterns.
----------------------------------------------------------------------
5. TARGET INTERNAL HARDWARE SPECIFICATIONS
----------------------------------------------------------------------
- GPU Model: ASUS RTX 5080 Prime OC
- Card Form Factor: 304 mm (Length) x 126 mm (Height) x 50 mm (Width / 2.5-Slot)
- Weight Support (2.95 lbs): Because a significant portion of this heavy card will now hang over the newly extended space, integrate a structural anti-sag floor shelf or heavy internal support rib into the nose of the extension to cradle the front of the GPU.
- Power Connection (Top 16-Pin): The ASUS 5080 Prime utilizes a top-mounted 16-pin power cable. The ceiling of the new 50mm extension section must feature an open interior cavity or increased vertical clearance to allow the power delivery cable to flex naturally without a tight, unsafe bend radius against the ceiling frame.
----------------------------------------------------------------------
6. MANUFACTURING MATERIAL & TOLERANCE SPECIFICATIONS
----------------------------------------------------------------------
- Production Material: PETG Plastic
- Structural Connecting Magnets: The extension body will secure to the chassis using raw circular magnets. Model flat, circular inset pockets on the internal mating lips/flanges of the extension piece.
- Magnet Dimensions: Sized for 20mm diameter x 1mm thick disc magnets.
- PETG Shrinkage Compensation: Apply a mandatory +0.15mm tolerance buffer to all pocket wall radiuses to compensate for PETG thermal contraction, ensuring the 20mm magnets can be press-fitted flush without fracturing the printed layers.
----------------------------------------------------------------------
7. VENTILATION & EXTERNAL MESH INTEGRATION
----------------------------------------------------------------------
- External Mesh Windows: To provide adequate airflow for a triple-fan graphics card cooling array, the new 50mm extension walls must feature open ventilation windows.
- Magnetic Tracking: Model a flat, continuous 1.5mm deep recessed tracking border along the outer perimeter of these new windows.
- Material Pairing: This 1.5mm depth must cleanly accept a cut-to-size MoKo 400x300mm flexible PVC mesh sheet mounted via its accompanying adhesive magnetic backing strip, resulting in a completely flush exterior side profile.
----------------------------------------------------------------------
8. REQUIRED FINAL DELIVERABLES
----------------------------------------------------------------------
Upon completion, the designer must provide:
1. An updated, solid-body parametric .STEP file of the modified enclosure.
2. High-fidelity production-ready .STL / .3MF files optimized for PETG 3D printing.
3. The native CAD file format (Fusion 360, SolidWorks, or original Onshape workspace link).
