I printed a big base for a model, but the corners of the bottom bent up, making the whole base rock when set on a table. Is there a quick fix for a makerbot2 without a heated plate?

**Tags:** makerbot, print-quality, warping

* Consider using a different material. Since you're on a replicator 2 you're probably not printing with ABS (which would be a terrible choice for a large, flat model) but probably with PLA. Perhaps you could try printing with PET(G) instead, which tends to warp even less.
* You could try modifying your model a little. If you include several grooves in the bottom surface of your model that may provide some "strain relief" so-to-speak, preventing warping.
* Increase adhesion: print your initial layer slower, closer to the build surface, at a higher temperature, with a brim, and with some kind of print surface to increase adhesion (tape/glue/hairspray).
* Increase ambient temperature. The Replicator 2 does not have a heated bed, but you could still make the cooling more gradual by enclosing the printer, shielding it from drafts, etc...
