Photon exhaust fan cowl

My example parts for an exhaust fume fan for my Anycubic Photon 3D printer. I have utilized a 60mm fan, a 40mm household push fit waste pipe elbow & a length of 40mm flexible corrugated plastic pipe from spares I had in the shed. The pipe simply hangs out the window top light. I may fit a carbon filter at some stage too. In practice I have no issues with fumes at all. Printed parts are simple designs in Auto 123Design.
