Basic 1in Mulit-Axis Tolerance Cube

thingiverse

An absolute necessity for any 3D Printer enthusiast! While basic in design, this cube model can be incredibly useful when verifying your 3D Printer's alignment beyond what you can see with the naked eye. For makers and hobbyists who create or learn to create custom parts for their projects, understanding a 3D printer's accuracy or tolerance is vital for more complex endeavors. It's well-known that commercial desktop 3D Printers often don't match their claimed precision. Knowing how much oversized or undersized a part will turn out can be incredibly helpful when designing components that need to fit together seamlessly. To utilize this model, simply align it with your slicer program's X, Y, and Z axes (or visualize the "Z" face if the x-axis is coming from the screen). Then print this block and use calipers to measure how close its dimensions are to 1 inch. With this cube, you can quickly determine your printer's tolerance and whether it differs across the three separate axes. In my case, both the X and Y axes showed an average deviation of 0.075 inches over 1 inch. Armed with this knowledge, if I needed a 1-inch part to fit snugly in a 1-inch slot, I'd undersize it by twice that amount to account for both parts' tolerances. Cheers!
