Hi,
I'm based in the UK, upon the other side of the world.
I'm able to print these for you if needed.
The package of the printed parts will be light in weight so postal costs could be quite low, might take some time for you to get them.
Have you tried your local maker spaces or Angus of Maker's Muse, he is based in Australia so closer to you than me?
Regards
Chris
