Circular Hole Tester

thingiverse

I often struggle with printing circular gaps where I plan to friction fit some component later on. I may need to ensure a part is tightly fitted, or verify it can slide smoothly without being loose, or possibly have something grip securely enough to hold but be easily detachable. When faced with such situations, I usually fabricate a quick block with some holes in it for testing purposes, but this was becoming an inconvenience due to its frequent occurrence. So, I created a parameterized scad file that allows me to produce them as needed. To utilize it, simply open the customizer and adjust the parameters to generate the types of holes you'd like to test out. Print using the settings you intend to use on your final model. Once printed, you can then test fit your parts in the various holes to determine which size is correct for your final model.
