Concentric Circles for Calibration
thingiverse
A customizable part that creates Concentric circles (open-ended) cylinders for testing and tuning wall thickness and consistency. All of my prints, particularly circular ones, had a "Mushrooming Base" problem where the wall was sucked from layer 2 up to about 5mm so I created an I created this OpenSCAD file to run tests with. You can select Cylinders or Base that will keep them together and test eccentricity. This is also a good illustration of how to create simple, modular and customizable parts in OpenSCAD. 2018.05.07 Uploaded new Base and OpenSCAD file to center the Base Slot Gap instead of just adding it to the inside of the slot.
