In any case, it would be useful if someone made thin washers that fit 1.25" filters so that filters that had deep male threads didn't extend past the rear of the filter wheel.
Thanks for share your experience!

So I thought I would post my experience as I have just received the 8 position filter wheel and a set of LRGB, Ha, OIII and SII Astrodon filters. The narrowband filters are not a problem, nor in my case was the Luminance filter, but the R,G,B filters were catching on the front case. As you say Turing over the front case fixes the issue.

Shown here is the outer case with the side that needs to go on outside in my situation.
Here is my set of filters in the wheel
