The Customizer doesn't work in chrome (at least for me)! It seems to work fine in Firefox.

If your print bed is not squared, checkout the rectangular version: https://www.thingiverse.com/thing:4579407

How To

This is a highly customizable bed level test. For a quick test of your liking, follow these steps:

1. Set the size to the size of your print area.
2. Set the line_height to your layer height.
3. Set the line_width to your nozzle_size.
4. Do additional modifications, if you feel like it!
5. Print it and adjust your bed accordingly.

Options Overview

size (100)

Defines the outer size of the biggest rectangle. Adjust this to match your build area.

min_size (10)

Defines the outer size of the smallest rectangle (If you think this is inconvenient, let me know!).

additional_rects (2)

Defines how many rectangles will be drawn inbetween the first and the last.

line_width (0.4)

Defines the width of a single line of the printer. This should match your nozzle's diameter. The total width of a rectangle is defined as line_width*line_count.

line_count (4)

Defines the amount of lines used for one rectangle. The total width of a rectangle is defined as line_width*line_count.

line_height (0.2)

This should match your desired layer height. If this is more than the layer height, the slicer might create multiple layers for the print!

star_count (2)

The mirrored count of the star stripes. When inspecting a single side, the side has n=star_count+1 stripes attatched to it.

star_start_rotation (0)

Defines the start rotation of the star_counts. Only useful, if your star count is 1 and you want to rotate the 4 start lines!

I hope you find it helpful!
