Rear panel with bayonet
This shows the bayonet mount fitted and the screws clamping the internal conduit through the rear panel onto the bayonet. A rubber gasket is under the flange to take up any small unevenness in the surface.
(Aside: Originally the plan was to install a small fan between rear panel and bayonet to push smelly air through the filter. The blower in the print area does a good enough job alone simplifying the arrangement.)
With hindsight I realise I could have combined the bayonet mount with the rear panel into a single printed part. This would guarantee no leaks - maybe a job for an updated print).
Bayonet is based upon another Thingiverse design (credit to www.thingiverse.com/thing:3681435). I sliced the rear part of the design off and merged it into the fan mount design.
