I developed this for my Dunu SA6 + iFi Gryphon using the 4.4mm pentaconn jack. Basically, it seems that the plug on the Gryphon is not exactly compatible with the plug on the Dunu which results in only one channel/side working. This little spacer fits on the plug and solves the problem.
I've been using this for a few months now and it seems surprisingly reliable!
I used ABS, but pretty much any filament will do. 0.2mm layer height is fine. It is a super small part, so make sure you print it solid.
