Lazy ducting adapter design, use some 100mm ducting as show in the photos and double side tape to the back. The ducting is a firm fit, so stays in easily.

We use a very low volume fan, 119 cubic metres per hour. Since air enters from all crevices flow over and around the bed and print doesn't seem to cause any issue.

Even with this low volume fan there is no detectable odour from ASA anymore, we will install an air quality and particulate sensor soon and I might even remember to update this model with those details.
