4 Days until Final Design Review

Touch-base meeting Sunday or Monday evening?
- Monday 8pm!
Mechanical team overview Wednesday or Thursday
- Thursday 8pm!

Goals

Set days for final design review
Finalize pending action items:
- Bonding testing
  - Updates to strategy
  - Plan for testing with current timeline
- Wheel integration plan
  - Load calculations?
  - Material choice?
    - PETG?
- FEA
  - Areas of focus, plan for timeline
    - Areas for FEA:
      - Drivetrain wheel hubs & Drivetrain wheel hub connectors
        Test with statically for buckling and vibration
        Test effect of heat on ABS connector? (Less of a priority)
      - Suspension
        Bending on bogie connector plates
        Impact on bonding tubes, specifically the fastener?
        Vibration on fastener + thread lock coming loose (Less of a priority)
      - Differential
        Impact of chassis forcibly wanting to tip
- Sponsored items update?
  - Get in by the end of this weekend!
    - Demtool only for pieces we can't machine in-house or that have tight precision
    - Demtool wishlist → EVERYONE TO DO
- CAD updates
