When I printed the first vertical stabilizer I noticed as it for closer to the top it was actually flexing it back and forth. This LWPLA adheres SOOOOO good I wasn't afraid of it coming loose, but it made the top 1/3 of the other one print a little rough (still useable). I figured I would try some quick 'supports to take a little of the flex out, tape, hot glue and popsicle sticks worked perfectly. I let the hot glue cool a little on the stick before sticking it to the tape, as I tried on a test piece and it will melt the plastic if it's full temp.
