The Ben Heck Show team have been stuck in a rut, mechanical design can be a sticky situation when you're creating from scratch - thanks to a competition winner the team can be unglued! When Ben created the Great Glue Gun it was given away as a prize, thankfully the winner still watches the show and sent it in to the team so it can be reverse engineered. Ben discovers the original design has some positives, using temperature sensing it can use intelligence around the glue being heated up, and it has negatives, it'll keep trying to push out glue, when there isn't any! So it's time to tinker with 3D printer extruder gears and take a lot of mechanical designs, rather than electronic, into account. Let us know what you think, and follow along on the element14 Community!
