Have you lost all cents of reality for 3d printing?!
Now you can spend as less time and money checking the accuracy of your prints.
Using this 3d printer test, you can quickly make a 3d print for testing IRL (in real world) accuracy using these four common coin sizes:
- United States one cent penny
- Euro five cent coin
- UK 1 pence
- Australian five cent coin
Things that can affect accuracy:
- Actual filament diameter: I’ve had some inconsistent filament diameter — over 1.95mm — throwing off prints that needed higher precision to fit properly.
- Speed: Too fast and corners can get rounded and filament thinned out.
- Flow rate: Too high and over extrusion can happen.
Square corners tend to round slightly due to filament width, so I added corner pockets to the vertical slots to offset this, and get a better fit test.
If your printer has a bit of elephant foot — first layer or two spreads out — then you may have to adjust your slicer, and/or start slightly higher above the bed, but risk first layer not sticking as well.
Let me know if you find this useful and helps you get better prints.
