Thanks I tried this in openscad… I was able to modify the diameter of the tool holder however when doing that, it makes it so that I wouldn’t be able to slide the bolts through because the diameter of 65mm is larger the mounting area, so the bolt holes have only a slight gap , not nearly enough to get the bolt through. I’m not sure how to go about modifying that further. There seems to be a second stl in that thingiverse item that has the bolt holes above the tool mount itself however there is no scad file to work with on that one.
Any other ideas? I really appreciate the help
