WHAT i BEEN USING IS eLMERS WASABLE STICK GLUE GOES ON PURPLE DRIES CLEAR. Has worked great for PLA, and THE first 3 eight hour PTEG prints. For bed leveling I use CHEPS gcode and ONE sheet of paper on a heated bed. I run a gcode of a PLA print with no problems. humiditry in print room is 53% right now. I had noticed earlier it was 49%. Just finished watching video of a guy made a dual roll heated dry box. Vairable temp heated pad, temp/humid guage, and can use the filament straigt out of the box. I also just spent 20 mins looking for same 11 litter storage container show in video. Only problem is it $20-$50 shipping from UK. Ill take a ride to local store to see if have something I can use
