perfect bed level test: fast, cheap, circle test 200mm

thingiverse

I was looking for a fast and cost-effective way to print a bed level test, but the other options on Thingiverse didn't meet my needs when I uploaded this design. This design is compact with thin walls, allowing it to print quickly - in fact, the time it took for the bed and nozzle to heat up was less than the time it took for the printer to finish printing this test. This makes it the ideal bed leveling test for 200x200mm because any effective test should be something that can be printed rapidly, inspected for problems, adjusted as needed, and reprinted without waiting several minutes between prints. A circle is the best design for bed leveling because if your bed isn't level, it will start to pull away from a circular path while creating straight lines - this doesn't happen with squares, so even if your bed isn't perfectly level, a square may make it appear that way. This test is 0.5mm tall, meaning the printer only needs to make two or three loops depending on the layer height - multiple passes are crucial because the second or third loop may reveal level problems that the first loop didn't catch. Wall thickness in Tinkercad is set at 0.1, which I believe translates to 0.1mm; printing with a 1.00mm nozzle worked fine for me. Being narrow and short clearly saves filament, reducing costs - this is also an important consideration when it comes to any test, as no one wants to spend more than necessary on testing. If you have a skirt setting in your print settings, it will print a skirt around the print, further testing bed leveling; the outer ring in the photo is actually a 10mm skirt loop with one layer.
