Free model configurator
A masking grommet made exactly to size
Enter the finished opening diameter, board thickness and flange diameter. We generate a parametric STL and immediately calculate the print time, material and final price.
How to measure
Measure the finished opening
A hole saw can leave an opening slightly larger or less regular than its nominal size. Measure the actual diameter in several directions.
Mounting clearance
A fit that does not need forcing
The configurator subtracts a small clearance from the sleeve diameter, so a correctly made opening should not require excessive force during installation.
Material
Clean-looking PLA by default
PLA is the default for dry interiors. In the calculator you can switch to PETG for moisture or ABS for warmer environments.
