Pi Camera Light Filter Holder

This holder secures a 1”x1” filter on the front of a standard 6mm 3MP Wide Angle Lens for Raspberry Pi Cameras. The filter slips into the pocket (held by friction), and then the holder attaches to the front of the lens via a simple friction mount. A Free CAD 1.0 compatible parameterized model is included here along with .stl files.

The DIY golf launch monitor project is using this filter to restrict the light entering a Pi Global Shutter Camera sensor to just infrared (IR) light. The filter for the project is a 1" x 1", Optical Cast Plastic IR Longpass Filter (1.5mm nominal thickness), but the model is parameterized, so the holder can easily be modified to fit other thicknesses (or sizes) by modifying the parameter in the “Master Document” spreadsheet named “'PiFilterHolderFilterThickness”.

Printing Notes:

PETG works better for flexibility of the holder, but PLA also
