I had to print a cylinder about 1”OD and 3/4” ID, hollow in the middle. Since there wasn’t much area touching the bed, compared to the height of the print, there is a tendency of the print to come off the plate. Simply draw a layer, in CAD, across the hollow in the middle about 0.005” thick. This will increase the area that will stick to the bed to 100%of the model bottom but can be easily removed after the print.

This is easily done in the slicer. Most slicers have ‘mouse ears’ as a added part or as a tool. It places a scalable disk one layer thick where needed. It might be easier if you didn’t design he file than bringing it into cad. I personally use mouse ears as much as brims. Any spot where adhesion might be an issue. A big part that has a few fine narrow components you can add a ear to he narrow bit ignoring the rest. Or if it is a complex shop a bunch or mouse ears where it is easy to remove and avoiding the hard area where removing a brim would be difficult.

I find brims and ears don’t always “attach” to the part even with the gap set to 0.00 where this part of the model and is easy to remove. If someone doesn’t do CAD then the mouse ears are the way to go.
