Any Zenobia 645 users?

If so, I have a question on film spool fit. On mine, the Arista and Ilford, that have the "X" type spindle holes, seem to be a mite bit too long. I have to file down the tiny raised lip on the outer circumference. The metal Kodak spools fit OK. Is this a common problem? Thanks for any input.

Forgot to add: Mine is the later type with Neo Hespar and Daiichi-Rapid.

I have to do the same thing with my Duaflex - file down the plastic spools and Kodak's plastic spools aren't any better than Ilford for a fit.

I have a Neo-Hesper Zenobia. Film spools are a tight fit but I haven't had to file anything down to insert them (maybe previous owner did?)
