How do we know what ABS you're using? And friction will be determined quite heavily by how smooth your print is.

ABS is not one material. Its coefficient of friction will vary widely. For example, BASF / Styrolution ABS is made by emulsion polymerization and is full of residual surfactant. That means that book values for COF will be meaningless for you.
Best to measure it. Take two pieces of your ABS, one on top of the other with the lower one fixed. Tilt them slowly until the upper one slides and note the angle. The tangent of that angle is the static coefficient of friction. Repeat several times to be sure.
Easy to measure the angle with a digital level as found on Amazon.
If you need to, it's possible to use additives to adjust the COF.
