Is this from a Lego set? Can anyone tell me which set this partial build is from?  Any help to identify it is greatly appreciated!
It's most likely that this is not an official Lego set. There has been such a piece (the purple ones) but it never came in that color, therefore it must have been manufactured from a clone brand. There could be that 00.1% chance of it being a piece from an official Lego set, but based on the poor quality of the build in the image and the fact that Bricklink couldn't find it, I still think it's from a clone brand. Also, if any of the plates have only specific studs with holes in them that aren't in a reasonable pattern (such as outline of house walls), then there's a big chance that the plate came from Mega Blocks and not Lego™.
