ABS Warping On Long Print

I've recently got a Kossel Mini and have this far used it for small prints. I decided to print some spare parts for it, but when I printer the first part, it took just over one hour and despite the bed being at 100°C and there being sticky substance on it (the residue from masking tape after being heated up to 100) there was a lot of warp on one end of the part. I have some pictures of it but I'm on my phone ATM so I'll upload them soon.

You need an enclosure around the printer to print large ABS prints without warping.

As a stopgap measure, you could throw a t-shirt over it. Without any kind of protection against drafts and the cool air, big ABS prints will warp.

Also, the heated bed being at 110 C instead of 100 would help.

Okay, thanks. I've been thinking of creating an enclosure of Plexiglas for the whole printer. Would that solve the problem?

You need to keep the electronics outside the enclosure

Very likely, make sure it is fully closed at the top since heat rises up and you get a chimney if you don't close it of.
