Modular rubber mats are generally strong enough to stay together on their own but high traffic, wet, or greasy areas can be problematic. After contacting the manufacturers, vendors, etc with no luck of any product existing I decided to make my own.
Designed and sized for use with NoTrax Cusion-Ease Drainage Mat ¾" Thick. Can be easily modified to fit other size/type mats
Simple print with no supports, plenty flexible and strong enough with PLA. Should be suitable in PETG as well. Cutouts allow a bit of flex as well as reducing required material.
Material: PLA
Layer Size: 0.3
Infill: 20%
Supports: None
Printer: Anycubic Kobra Neo
