After 6 hours, print curls and crashes

Hi All!

I'm new to the whole 3D printing process, I was trying to print a little holder I found on thingiverse using their exact recommended prusa settings. However about 6 hours in to the print, if has this section that curls up and causes a crash and the print to fail.

I'm not really sure what to do here, I have no clue what's causing this, so any help would be appreciated!

Its not clear in your first post, but if you're having curling on the top surface on large flat-ish prints its probably from differential cooling. I've been working on a model of the Enterprise from startrek the last few days. The main hull, the disk part at the front, kept curling, and catching on the extruder tip, and ripping it off the platform.

It was just from being kinda sorta near a very cold window. Weather has been shifting here from 45 during the day to 15 at night, so what worked during the middle of the day failed overnight or when it rapidly cooled outside. I just took a small space heater, placed it behind the printer, pointing straight down the Y axis, and on the lowest possible settings. The board and psu aren't getting hit with air. Prints have gone fantastic since doing this. 

Been printing the last 50hrs or so continuously without issues

This is what comes in the box, so I guess it's prusament PLA and on the smooth metal surface?

Clean bed with dish soap.

Adjust your z layer height.

Both settings need to be 100%, this helps to get a good model and that model sticks to the bed.

 

Then if you print and have warping:

use a big brim attach to model, 8 lines,

use glue stick,

Extra you can try, first layer hotter and slower,

bed a little higher if needed.

Keep wind of the printer.

If you have a enclosure leave door open with PLA.

 

Make a first layer for the forum, make a picture and put this on the forum.
