Stark Varg Charger Case

Design Objective

The objective was to reverse-engineer and fabricate a high-durability, compact replacement housing for the Stark Varg electric motorcycle charging unit. The design prioritized volumetric efficiency and improved field-ruggedness compared to the OEM enclosure.

CAD & Modeling

The enclosure was modeled from scratch in Onshape. All dimensional criticalities were captured via direct measurement of the OEM unit, ensuring precise alignment for thermal ventilation and electrical interface ports.

Manufacturing Failure Analysis

Despite the maturity of the CAD model, fabrication was unsuccessful during the initial prototyping phase.

• Root Cause: The Ender 5 FDM platform utilized for the build exhibited significant dimensional inaccuracy and thermal warping during high-tolerance sections of the large-format print.
• Outcome: The printed components failed to meet the required assembly tolerances, resulting in project suspension.
• Conclusion: The digital architecture is sound; however, successful execution requires a manufacturing node capable of higher dimensional stability and better thermal environment control (enclosed build chamber).
