The inspiration comes fromThe octagonal spring of @nokiri。"NokiriThis spring is very practical, and I have already applied it in some of my designs.

But in some cases, square springs are more suitable for the design, and at the same time, we need larger and stronger springs, so I adjusted the parameters.

Spring design parameters:

• Shape: square and hexagonal
• Dimensions: 20(width) x 20(length) x 20(height) mm
• Thickness: 1.6mm

• Number of laps: 3 / 4 / 5

  (The fewer the number of turns, the stronger the resilience)
