Parametric Cup Protector – Universal Fit for Thermal Cups

Tired of scratched surfaces, noisy cups, or poor fit protectors?
This parametric cup protector is designed to adapt perfectly to your cup, no matter the size.

With fully customizable diameter and height, you can generate a perfect-fit base protector for thermal cups, tumblers, mugs, or any similar container.

 Features

•  Parametric design – adjust diameter and height to fit your cup perfectly
•  Universal use – works with thermal cups, tumblers, mugs, and more
•  Surface protection – prevents scratches on tables and countertops
•  Noise reduction – softer contact when placing the cup down
•  Improved grip – reduces slipping on smooth surfaces

Materials

•  TPU (recommended) → flexible, better grip, shock absorption
•  PLA (works) → more rigid, still protects surfaces

 Customization

Simply adjust:

• Inner diameter → match your cup base
• Height → increase for more protection or stability

You can quickly adapt the model to different cups in just a few clicks.

 Notes

• Designed and tested with a real thermal cup (see photos)
• Slight tolerance recommended depending on your printer settings
• TPU provides the best performance, but PLA is a viable option
