Bed Cooling Adaptor for Bionaire Filter

Designed to sit on a Bionaire BAP9921 air filter, allowing you to use it for cooling your steel sheets (otherwise they tend to float off to the side…).

It also makes your air filter the King of all Air Filters.

I printed it with the pointy end up out of HTPLA, but that will require supports underneath.  Alternatively, you could use your slicer to cut the bottom ring off and print that separately.
