JBL Horn Tweeter Stand

My first functional print using TinkerCAD. I am adding an active JBL horn tweeter to my Fostex BK-16 folded horn. With this support I can shift the tweeter back and forth to get the drivers in phase. When I am satisfied I will mount it permanently with epoxy to make it cat and childproof.I am using a MiniDSP 2x4 sound processor and a UMIK-1 measurement microphone to set it up.The folded horn kit:https://www.madisoundspeakerstore.com/full-range-speaker-kits/fostex-bk-16-folded-horn-kit-pair/The tweeter horn:http://www.jblpro.com/www/products/selenium/hm25-25The tweeter driver:http://www.jblpro.com/www/products/selenium/d220-ti
