Easy print.  The chainlink has built in support ,other parts need support. I will provide the rest of the parts with built in support… 

Print with ABS 0.2 or 0.12 Layer height and should be fine…

Nozzle 250 Bed 100 in my case…

You can open the chain and close it again if maintenance needed.

Improved Parts, No Built in support, I use Prusa TreeSupport instead.

Stronger End part.

/Kept the old version with Built in support/

The New version in file:

Chain_10x11_X.3mf

The latch need to print 0.12 layer height, other parts 0.2( thanks for the review)
