15mm Rod Shifter for Matte Box.

To fit the non-standard baseplate to the standard matte box, we need to shift the rods by an appropriate distance. There's some Rod-Shifter in the market, but they're too long or too short for me.

So I designed this 3d model for an 18mm distance. You can modify this model with DesignSpark Mechanical on your own.
