what color filament is in the pic? I like it

I dont understand this test. If a nickle is 21.21 and this is printed at 22 then one would expect that the nickle will fit in easily which mine does. Shouldn't it be a 21.21 print and then you can resize up and down from there to dial in the calibration or am I misunderstanding the intent of the way this model has been sized?

Most machines have a tolerance of 0.4 mm this is just a test of roundness of your machine

What would the outside dimensions be? I am wondering if I am over extruding.

I have tried various test and calibration prints, this one suits my specific situational needs perfectly.

Thank you for creating this, and linking the measurements you used.

If you are ever in Secure Bunker, Nebraska... I owe you a beer.

I'll take you up on that

Um that is 0.79mm tolerance, not 0.69

It would be helpful if you put up some instructions on how to calibration you 3D printer if it does not come out prefect :)

Things change so fast in 3d printing. Refer to your machine's documentation for calibration

I've added a link to the instructions to help with calibration.

Really smart idea!

Brilliant! Really. I think this is the best calibration piece ever.
