For me I buy a flexible exhaust hose (100mm) and a duct fan at Amazon for small money. I have a small dog flap near my Ortur Laser and I can adapt the fan in seconds on this door to blow all outside.
Last week I bought carbon filters for kitchen exhaust hoods and I think I will put that in the exhaust hose too. Maybe it will not smell and amoke then on my terrace.
When I´m finished my enclousure I can show pictures if you want.
The orange colored plate can be found at www.modulor.de as a acrylic 3mm version. But it´s expensive I think.
Yes they are quite expensive, unfortunately I can not figure out where I bought mine this time.
