Prusa Mini detachable cooling duct
prusaprinters
I had problems with printing overhangs on small models printed in PETG. Thats why I tried Boothyboothy's - Prusa Mini Detachable Cooling Duct Assembly V2. But still had problems while printing overhangs on small models. So I tried to put more holes to cooling duct model to improve airflow. Im not sure if it helps or not while I made also lot of changes in prusaslicer, but curretly Im able to print my models without problems. The only problem with “Prusa Mini Detachable Cooling Duct Assembly V2” is clearence to original hotend and duct is little bit sagging when priting PETG. So maybe I will try to print it with something more temperature resistant than PETG or I will return to original prusa mini solution. I really dont know now.
