Superlux HD681 mod replacement rings

I did not like the red rings on my Superlux HD681 so decided to change the look by print some new replacement rings.I chose silk silver PLA filament for a metal look. With an as low as possible layer height it gives a nice metal look finish. The old rings can be removed with a sharp knive.Disassembling the headphone is not required, when you squeeze the big ring a bit when it is loose you can slide it over the earcup.I personally did not use any glue but this is optional when assembling.
