Small Bolex Matte Box

This is a design for a small matte box for Bolex cameras. It's a preliminary attempt at making a simple matte box for holding filters in front of a lens.

Attaching to the hot shoe mount on top of Rex-series Bolexes, this relies on a rectangular brass tube as a rail to hold the matte box. It expects a 3/8" x 3/16" (4.75mm x 9.5mm) profile for this rail. There is also a printed version of the tube included as an 3D-printable STL file.

The hot shoe mount + rail design was also adapted by Lindsay McIntyre to hold an alternate matte box for use with 4x5.5 inch cards.
