Dangerous Ladies' 3D models for basic calibration tests for printing cosplay weapons.
Model by Jennifer Rezny (@quicksparrows)

.stl format. Should fit on any printer.

These are tools to test various things about your printer.

CALIBRATION CUBE:

• This is a cube you can print to test that your prints are dimensionally accurate. It is exactly 1x1x1"; if you print it and find one side is longer or shorter than it should be, you'll know that something is off about your printer's belts, and it's not printing accurately.
• There are a lot of free calibration cube files on the internet, but we did ours a little different; we've got text on ours saying what side of the printer the cube should face. Most cubes have X Y Z printed on them, which is fine, but a lot of us struggle to remember which way the X axis runs. This way, you can see whether your printer is off left to right, up and down, or back to front.

KEY TEST:

• This tests key slots. The test print has a 0.2mm tolerance on the key and 0.5mm of extra space at the top of the slot. The vast majority of our files have a 0.2mm tolerance.
• If you find that the resulting print is too tight, your printer may have too much wobble, leading to shaky tolerances and dimensional expansion. (Basically, your printer belts are off, OR you're printing so fast that the lines it's printing aren't accurate.) Try to reprint slower to see if it improves.
• If you find that the top doesn't comfortably snuggle all the way down onto the bottom, your printer struggles with overhangs and the underside of supports. Try changing your support or bridging settings to see if you can get finer results.

DOWEL SIZER:

• This tests the true dimensions of your dowels. Dowels are not actually wholly uniform. Some companies producing dowels have inconsistent tolerances that make the dowels sometimes as much as 0.2-0.5mm narrower or wider than they're supposed to be.
• This test also assumes your printer is dimensionally accurate. If your print isn't accurate, then this test is meaningless.
• Bring this to hardware stores with you and poke the end of dowels into it to see if they are truly 1" (2.54mm) or if they fit better into something with a bit more tolerance (26mm) or are wildly out of whack. (27mm) You can also use this as a guide for printing; if you find your dowels are consistently larger than they're supposed to be, you can print files at 101% or 102% scale to give yourself a little more room for dowels without adding too much length.
