Think I’ll use this screw and rod for my Z-axis. 180mm an overkill? 
you may wanna upgrade to a larger nozzle, while you’re at it.
@Mike_Miller uh, thats gonna be complicated, since you wont get filament larger than 3mm… ^^
well, 3mm’s a start, perhaps we can get it to coil up in the hot zone?
LOL
You’d need 220v mains direct to power that hot zone!
LMAO!
Build area 5x5x5m
So…you will be printing in concrete or wood pulp with binder agent?
Overkill is underrated.
You can probably get by with just using those bolts holding the rod to the coupler as a z rod 
@James_Armstrong you can get by with rice and beans, but every once in a while i want steak.
Don’t forget to reinforce your floor, building table and the rest of the building…
