Air vent deflector for the Truma Combi RV heater. Much more robust than the "lamella" deflector. Printed with polycarbonate so it can handle the high air temperature. Snaps in and rotates to adjust the direction of air flow. There is a slot for removing it with a coin or flat bladed screwdriver. Available in Black and "Silver".
There is also a version with a grid screen on the intake, designed to keep mice out of the Truma. The spacing between the deflector vanes and the optional grid is 8mm.
Update: There is some data that shows that smaller mice might be able to get thru an opening larger than 6mm, so I added a new versions with a smaller 6mm vane (and grid) spacing. It takes longer to print, so it costs a little bit more. You decide which version is right for you...
