Screen Customizer

Customize screens to fit your holes using this tool! Whether you want to keep out varmints or bugs, this customizer allows you to create perfect-fitting screens. Check out this example (http://youtu.be/4u0x-dLiKdw) of soffit vents printed for a house using the tool. The creator even printed 97 of them in total for their home. When using the tool, ensure that you select the indentation setting that suits your needs - printing the outside face of the screen down on the printer surface or the inside face. Don't forget to match the screen and slicer tab settings with your slicer for better results. Surprisingly, entering a diameter works well even for square screens as it allows you to create square shapes effortlessly in OpenScad.
