Here is an STL for anyone wanting to use a 4inch (100mm) ventilation hose on the back of the Form 4 to evacuate odor. I use a 4 inch hose to a carbon/HEPA combo extractor that helps significantly reduce odors coming from strong resins like Tough 1500 and 2000. I printed this in PETG on my PrusaMini+, 15% infil with supports. Use a zip tie (cable tie) to secure the hose to the indented rib.

are you guys running these on your desk in a office because we never smell anything unless we get close to the tank or after the cure? ---

I have a very small studio in my basement, and the odor is noticeable with the Tough resins. I smell nothing when printing Black V5, so don’t need to run anything for odor. There is a ‘cooked’ odor with Tough2000 after curing/baking for an hour ---

Very nice, thank you very much for sharing ! Is there any chance you could share the source file so we can adapt it to our output diameters? ---
