Printing (mostly PLA) in an unheated garage. Will the cool temperature and mild fluctuations affect my prints?

Will putting my printer in the garage be a bad idea? It’s unheated, so the temps will be cool in the winter and hot in the summer. There will be some occasional drafts when the door to the house is opened, but I doubt I’ll have the garage door open very often. I mostly print PLA. Is it necessary to build an enclosure, or will I be ok just printing in the open? Thanks! http://ift.tt/2dYZaP9
