Ultimate First Layer Calibration Patterns

thingiverse

After having some first layer troubles, I decided to write an OpenScad file to generate various first layer calibration patterns. Just edit the attached OpenScad file and remove the comment in front of the pattern you're interested in OR download one of the pre-rendered STL files (they're for a 250x210 mm bed). You can also combine multiple patterns by un-commenting multiple lines. If you have a pattern idea, please drop a comment and I'll try to include it in. 2018-04-30: available patterns are: full bed, bed corners, bed middle sides, bed outline, inscribed circle, chess board pattern, bed quarters, bed cross.
