Assembly Tips

• Friction is the main challenge. Ensure all parts are smooth and free of strings. A heat gun or torch can help remove imperfections.
• During assembly, test each moving part. If anything sticks, consider sanding or identifying where it’s catching.
• While the OuterGear works best with 80% infill for weight, tests show it can function with lower infill if the system is smooth enough.

Update: The CentralPin.3mf for the tachometer has been adjusted to prevent the needle from sticking on certain numbers, especially when tested lying flat. If you've downloaded the design before 2024/12/02, please redownload the updated file.
