Colorfab steelfill, it's not to hard to find but I got mine from Printed Solid. They are pricey compared to other vendors but there was no wait when I was ordering.
Printed on a .6 hardened steel volcano nozzle from e3d. I don't have a dual extruder at the moment so supports were done in the steelfill as well. Pre support removal one side was 402g, with it removed it dropped to 270g.
Keycaps are a generic set from Amazon.
