I may have gone a bit overboard in designing some CAD sketches of the XL and touch probe to help me build the cart that mine now lives on. I couldn’t find other resources for the XL, and my free account at Onshape dictates that these are public files, so I thought I’d share them here in case there are other Onshape users. Where possible, the designs are based on the available CAD drawings from the wiki, with my own measurements filling in the rest (e.g. the maximum cut area is measured with a metric ruler against the min/max movements CarbideMotion could move my C3d router and a 1/16" bit).
