Size changeable linear bearing done in freecad.
Inner and outer radius.
6 holes change the radius accordingly.
Don't have a clue on how todo full parameterisation, but as I get better of course quality of Freecad file will get better.
Found that in PLA their is usually about 0.2mm shrinkage in overall diameter. So this needs to be accounted for.
Found that once shrinkage is accounted for, a typical freeplay of about 0.05mm in the radius is possible. Some teasing of the part to get
