I am familiar with those laser collimators.
Are you using it as a 2" unit or 1.25"?
How are you finding it not fitting snug?
I need to ask these Q's so we can give the best solution.
If it is a little loose, a wrap or two of sticky tape often does the trick. Another is to push it onto the focuser drawtube when you tighten the set screw. This way you assure that it is sitting square on the drawtube.
