Kerf Test
We tested the kerf using a 20mm width square cut. After laser cutting, the remaining inner square measured 8.15mm, indicating that the kerf was approximately 0.4mm in total.

Progress
Experiment 1: Wheel Design
The first attempt used flexible joints on the wheel’s side panels to provide structural support. However, the slots were too narrow and unstable, causing the wheel to deform during rotation.
The wheel design was revised to use interlocking slots on the side panels, which significantly improved stability and allowed the wheel to roll smoothly.
Experiment 2: Joints
The joint connections were still unstable when supporting the full structure. Slot dimensions need to be refined to ensure a more secure fit between the walls and wave components.

Learning from Failures
- Material Matters: Cardboard surfaces generate too much friction when rotating against each other. It's crucial to evaluate the mechanical properties of materials for moving components.
- Parametric Design Matters: Use critical measurements, like kerf width, as base parameters. Designing components relative to these values makes the structure more consistent and easier to modify.
