Just a few simple cylinders to help keep finicky corners down on the build plate if they're misbehaving. Some slicers (like PrusaSlicer) have this function built in, so you should use the native functionality instead.


I have included a series of mouse ear models ranging from 2mm-64mm radius with a 0.2mm initial layer height. The .scad file can be modified parametrically for other layer heights and sizes.
If using Cura (or a derivative thereof), you must disable the Ensure models are kept apart setting under Preferences > Configure Cura > Viewport Behavior and the print mode must be All at Once under Special Modes.
The model used in the screencaps is Curved Crossing Track - H3 by @MichaelFanta.
The author marked this model as their own original creation.
