This is a simple print to help level the bed.

Scale it to fit on your printers bed. If the print is too 'squished', your bed is too low. If the print is 'squiggly', your bed is too high.

Adjust as necessary.

v2 now is scaled at 100mm x 100mm x .1mm Each line is 1mm thick. Removed the center of the square to save time as its the corners that matter most.

When you're scaling this model to match your bed size, be sure to adjust the z scale to match your layer height. If its .4mm, then multiply by 400%. If its 0.175mm layer height, multiply by 175%.. etc...

If your bed dimensions are 150mm x 200mm, you'd scale the object by 150% and 200%. If your bed dimensions are 200mm x 126mm, you'd scale the object by 200% and 126%.

Makes it very easy to scale for your bed size.
