New Zealand Conduit size for ZenXY V 2

Has anyone in New Zealand built a ZenXY V2? needing to know where you bought conduit tubing to EMT standard, 1/2" EMT conduit, outside diameter 17.95mm and 3/4" EMT conduit, outside diameter 23.5mm. I can only find 1/2" and 3/4" conduit to ANSI C80.1 standard which have diameters 21.43mm and 26.67mm respectfully. Alternately suppliers for 18mm and 25mm conduit.

Ryan has a mix if the ZenXY v2 for metric countries using 25mm and 18mm tube

Thank you Dan, I’m also considering 18mm and 25mm, I just need to know where I can purchase in New Zealand. I was able to use 25.4mm tube for my Primo and Lowrider 3 which was readily available. May have purchase from another Country.

I was able to locate both 25mm OD tube and 18mm OD tube, however it seems 25mm OD tube and 20mm OD tube is more common where I live.

I have some parts but I’ll reprint them asap.
