3D Printing straight onto glass with PLA

A couple of weeks ago I cracked a pretty big personal milestone with 3D printing; extruding PLA straight onto glass. Without blue painters, or kapton tape. This had been a pretty tricky problem to solve - as getting the first layer of plastic to bond to your print platform is one of the hardest nuts to crack when you first embark on the 3D printing journey. I had all manner of issues with plastic curling, knotting and perfectly good prints getting knocked out of place mid print. But no more!
