Hi I am building a saber using the Darth Maul MR FX empty hilt. I plan to run a tri LED so I am using a NB V2 and extender. What can I use as a speaker holder? I had ordered a MHS speaker mount V6 - For 28mm Speakers but the diameter at the end is too large. Is there a holder I can get before I try to remove material from the diameter?

Thanks!
