Kinetic Moire pattern coaster / fidget

Fascinate your guests and protect your tables with these mesmerizing Parametric Moiré Pattern Coasters! This clever two-part coaster design features a solid base and a rotating top layer. Give the top a quick spin to unleash a stunning optical illusion of moving shapes and lines caused by moiré interference.

Designed entirely in OpenSCAD, this model is 100% parametric and fully customizable to suit your style, your mugs, and your 3D printer's tolerances. Whether you want a simple linear illusion, a hypnotic swirl, or an intricate labyrinth, these coasters double as a functional home accessory and incredibly satisfying fidget toys!

⚙️ Customization Guide

Because this model is fully parametric, you have total control over the design! Adjust the following key parameters to make the coasters truly yours:

• General Dimensions:
  • coaster_diameter: Set the perfect size for your cups or mugs.
  • base_thickness & pattern_thickness: Adjust the heft and sturdiness of the coaster layers.
  • rim_thickness: Tweak the outer border size to keep condensation trapped securely inside.
• Pattern Details:
  • pattern_type: Choose between three fantastic optical illusions: Lines, Swirl, or Labyrinth.
  • line_width & gap_width: Modify the density of the pattern to subtly change the visual interference effect.
• Mechanical Settings:
  • pin_on_base: Choose whether the central spinning pin is attached to the bottom coaster or the top spinner!
  • tolerance: Need a smoother spin? Adjust the slip-fit clearance to perfectly match your specific 3D printer's calibration.
  • pin_extension: Control exactly how far the central pin protrudes through the top layer.
