A simple test piece for your printer, test the flatness of your bed over a 60mm2 area, your steps per mm and the ability of your printer to cope with xy feature detail.

We thought it would also make a nice decorative piece, show you friends that you are a Maker.

The piece is 60mm x 60mm x 7mm, this size means that you can test the flatness of your bed and bed adherence. The lettering will give you a good idea of how well your printer deals with XY feature detail.

We created the model by importing our logo as a .SVG file into Freecad, the techniques used are the same as in our guide on creating a 20mm 3D printer calibration cube in Freecad ( https://www.idig3dprinting.co.uk/news/how-to-guides/create-a-3d-printer-calibration-cube-in-freecad/ ) . The results that you see here we tested and printed using a Prusa i3 loaded with 3Dom filaments Ingeo PLA ( https://www.idig3dprinting.co.uk/product-category/3d-printer-filament/?filter_filament-type=129 ).

How to calibrate your Steps per mm on your 3D printers axes:

You can calibrate your printers steps per min for the different axes by:
e = expected dimension (y = 60mm, x = 60mm & z = 7mm )
o = observed dimension
s1 = current steps per mm
s2 = new steps per mm

so that

s2 = s1 x (e/0)
