** Be sure to print with the vacuuming surface layed flat, for the general purpose and the water extractor. For the crevice tool, make the vacuuming tip facing up.

General purpose shop vac attachments. There is a wider, general purpose one, a thinner water extractor, and a finer crevice tool.

You could probably scale the models to make them fit different machines. The general purpose one has 5mm wall thickness, while the other two have 2.5mm wall thickness.

I used 3 walls and 75% (PETG) to make them tough.
