Longer Z axis

Hi all,

haven't visited here a while, mostly due to the fact that my Hadron just works :-)

But now I have a print that I have a problem with. It's just slightly too tall. It's the Easy Printing Electric Violin,, by firecardenal. It is almost exactly 20cm tall, and my Hadron is able to do 19cm max, even with longer couplers and all. I could make do with hacks, like putting a thick shim underneath the extruder holder, but I'd much rather do things properly. So it looks like a longer Z axis is in order.

Unfortunately, most of the webshops don't carry the Hadron anymore, and certainly not any upgrades. Can you guys give me a hint where to get longer lead screws? They are not regular M8s, are they? So simple threaded rod from the hardware store is problematic, right?

I installed a pair of these ACME threaded rods ... 80650.html
They give me 195mm in Z height but I have the Z axis anti-wobble devices fitted which remove about 25mm of travel.
This is with a J-Head hotend that extends below the X carriage by 15mm
