WIP hot glue bump tutorial

1. reset the device *press enter key and disconnect power
2. align where the bump will be with gravity and generally aim the glue gun opposite gravity
3. get coverage starting from the top *wrapping the glue around the screw head
4. end with the glue you need for the bump before lifting up and off to round it out
5. use the side of the nozzle to reshape as needed
