This is an update/alternative to my previous model. After some use, I redesigned the model to make installation significantly easier, more precise, and aesthetically pleasing.
The model can be installed by pressing it onto the filter or using a small amount of CA glue.
Press fit tip: Adjust the scale according to your printer's tolerances, original model is loose fit tested on Prusa MK4.
The spacer rings are used for precise positioning of the exhaust. Place the spacer ring on the end of the filter (where the filter touches the vacuum cleaner) and then align it with the edge.
Warning: The spacer rings and the air duct may scratch the glossy surface of a new filter.
The author marked this model as their own original creation.
