Box Fan Filter Holder for 2" Filter

For an upcoming build of a variable speed box fan with filter setup I've modified this design to accommodate 2"x20"x20" filters on a box fan.

You'll probably want to print it out of PETG, if possible, for a bit of give in the plastic when clamping it on.

I've now got the video fan box filter with variable speed controller build up, Video and Article here:
