Califlower Calibration STL by Vector 3D [Digital Only]


The Califlower STL file and calculator to help you with printer calibration and testing.

SKU: 3YZEM3 Categories: ,
(6 customer reviews)


The “Vector 3D Califlower Calibration STL” is an STL file to help you with printer calibration and testing. Included is documentation in the form of a spreadsheet calculator to identify and correct printer scale and skew accuracy.

Includes the Califlower calibration STL file and Calculator Spreadsheet (in Excel and Libre office formats)

Please note: If you work with a numerical system that uses a comma (,) as the decimal separator then you will find that the spreadsheet places commas where the firmware requires a full stop/decimal point. For example, 10.45mm will become 10,45mm. See this Microsoft help document on how you can temporarily change this to use different separators…

Do you need this?

There is only one printer that I know of currently that has an in-built method of skew correction which is the Prusa Research Mk3 and its variants. You could still benefit from the Califlower as a test to prove that the in-built method is working.

On the other hand, the Prusa mini, to my knowledge at this time, has no methods for correcting skew. You would need to break the appendix on the control board and write custom firmware to implement it. Again, you may benefit from the calibration flower as it could help in knowing the extent of the problem with skew, and may still assist in manual correction, it’s just not as simple.

As far as I know at this time, most other printers are easy enough to flash firmware to, or have simple implementation methods for scale and skew.

    If 3D printing parts accurately is important to you, then this calibration suite is mandatory! I donโ€™t run a printing farm, and itโ€™s still worth every cent for me!

    great calibration tool! Sadly I have a prusa mk3 and dont know how to feed te correction code yet

    Very nice tool =)

    This helped me calibrate my printer after making some heavy modifications. Highly recommend! I’ll be buying the cali lantern next.

    Awesome print. Actually getting it to print properly was the first step in calibrating my newly purchased printer.

    I only had small corrections to make but have been printing very accurately since, for example a tight-fitting mod for the cooling fan duct in my printer.

    I am extremely pleased with this. The price is well deserved and it makes calibration significantly easier, especially when it comes to accounting for skew in the printer’s frame.
    On my modified Ender 3 this allowed me to reduce the skew from 0.39 degrees to 0.04.

    If you are on the fence about it, I highly recommend giving it a try
