WIP hot glue bump tutorial

reset the device *press enter key and disconnect power
align where the bump will be with gravity and generally aim the glue gun opposite (pre-heating the screw head will help the glue flow)
get coverage starting from the top *wrapping the glue around the screw head (until it's just touching the threads)
end with the glue you need for the bump before lifting up and away to round it out
use the side of the nozzle to reshape as needed
