Impact-Resistant Electronics Enclosure Prototype

I need a sturdy, impact-resistant plastic enclosure that will safely protect a circuit board and a battery pack. I already have rough dimensions and mounting points sketched out, but I’m counting on you to refine the design, create full CAD files, and supply a single 3D-printed sample so I can test fit and durability before moving to tooling.

The enclosure does not have to be waterproof or vented at this stage—the priority is a clean, professional look and the ability to absorb knocks without cracking. Snap-fit or screw-together construction is acceptable as long as the board and battery remain secure and serviceable. Typical wall thickness targets are 1.8–2.4 mm, yet I’m open to recommendations based on the material you choose.

I work comfortably with STEP, STL, SolidWorks, or Fusion 360 formats, so provide the native file along with export versions ready for printing. If you can include basic FEA or drop-test simulation screenshots to justify ribbing and support placement, that’s an appreciated bonus.

Deliverables
• Finished 3D design files (native + STEP/STL)
• One physical 3D-printed sample shipped to me
• Assembly instructions or brief notes on fasteners, tolerances, and material used

I’m ready to review your ideas and move quickly once we agree on the final outline.
