I am using a pop up drain as the hilt for my lightsaber. having issues fitting and holding blade in place. any advice on other popup drain builders. I think the 1.25 blade holder from custom is a little too large for the top of the opening. I am using a ultimate fx luke rotj sound board.

any advice as to what led I need to get? As you can tell I am a noob and I appreciate any good counsel. Thank you.
