Baader filter crown tool for changing 2" filters

Baader 2" Filter Crown Tool

The 3D-printed tool makes it easy to unscrew 2" filters that are difficult to access, for example in filter drawers. It was designed for the 2" low-profile filters from Baader.

Modern filter cells are very thin-walled to provide the largest possible clear aperture for the actual filter. This means that the cell can easily deform if too much pressure is applied, causing ist to jam and making it impossible to screw in the filter. With this 2" filter crown tool, the pressure is distributed over a large area so that the filter cell cannot deform. The filter surface is also better protected.

The filter crown tool is specially designed for all mounted Baader 2" filters. This is due to the unique design of Baader filter cells, which feature a precisely milled "filter crown". The filter crown tool interacts with this special notch and is effective only when used correctly. Due to these features, the tool is not compatible with filters from other manufacturers.
