This is a collection of M3 washers available in two dimensions 1mm and 2mm, the 1mm version is meant for parts with less clearance on the sides.

.32mm (1mm nozzle)

In order to decrease stringing and prevent bed adhesion issues, I highly suggest using the "one at a time" print sequence mode on your slicer (it's called exactly that "Print sequence" in Cura).

Tolerances should be good, having a .1mm extra hole size should make these models printable on practically any printer at any quality. I've personally used a 1mm nozzle without much trouble but a few blobs that I could easily remove by forcing the screw in using my hands.

These models were designed on Tinkercad based off the standard thread size for M3 screws and a bit of trial and error to mitigate clearance issues.
