cut print doesnt align when put together
I haven't seen this problem before on my MK3S but then again I dont usually print things so big that I need to cut them into parts.
This "snail" shell (see video) was cut in two and printed but if I align the two pieces on one side, then one piece sticks out something like 1-2mm on the opposite side, so one piece is longer than the other. I believe this is along the y-axis.
What causes this and how do I fix it?

These are the two prints in Prusaslicer...

Sorry it seems the link to the video didn't work...

Warping is not uncommon in larger prints. The two main controllable causes are:
Premature removal from the printer - let the part cool completely before removing it, large prints take longer than you realise to finish cooling internally.
and heat stress during printing - drafts or a generally cold room cause uneven cooling, usually the front and back of the print are wost affected as the moving bed moves them in and out of the warm air rising from the bed. The long term fix if you are planning a lot of these is a cabinet; the quick and dirty fix is a large cardboard box placed over the printer to make a temporary enclosure.
Hth, Cheerio,

@diem
I did remove one of them immediately but it seems like a lot of warping for an almost solid piece (60%infill)

@andreas-6
Cut the infill to about 10% - 15%.

Diems advice on temp rings true with issues with large prints warping on my old ender.
The room temp was dropping at night (it's cold in Scotland...lol) causing the warp, I ordered an enclosure but have not had the chance to test yet, hoping it will fit my new MK3 when it arrives.
Tank you very much!
