E3D Hobb-Goblin

Just Some Fun! A while ago, someone posted on Twitter a picture of a curiosity they found on the E3D website: the Hobb-Goblin. Huh? Hobb-what? The Hobb-Goblin is a brand of hobbed gear sold by E3D and has its own mascot - a scowling hobbed gear. I suspect the look is that of determination, not one meant to scare people. (My kids think it's adorable.) The Hobb-Goblin is an in-house creation of E3D. I loved the design and thought it would be fun to make a printable version. That's why this is here now! What is a "hobbed gear"? School time! For those of you who have assembled your own printer, this is probably pretty familiar to you. To those of you who haven't, the hobbed hear is a part of your extruder (the "cold end") that bites into the plastic filament in order to push it through the hot-end so that it can be melted and subsequently squeezed out the nozzle (the process of extrusion). It has a very important job and if there is a blockage or the teeth can't bite in (due, perhaps, to a bunch of chewed filament in the teeth), you'll hear the familiar "clicking" sound of the filament slipping in the cold-end. Brush your hobbed gear's teeth regularly, girls and boys. OK, so who are E3D? E3D is a company that manufactures the parts that make your FDM printer work. Chances are, you have a hot-end and/or extruder that was manufactured by them, or inspired by them. Their designs are widely emulated (or outright copied) by many, many manufacturers. However, there's a good reason why many swear by E3D - their stuff works and they stand by their product. So, can I use this on my printer? Heck no. But you can put it next to your printer for fun. (Or perhaps to supervise the little brass gear on your printer.) Final thoughts... This was not sponsored in any way by E3D nor am I affiliated with them. I happen to like their company, their people, their business practices, and their philosophy. Again, the Hobb-Goblin is an in-house design of E3D. They were kind enough to bless my posting of this model on Thingiverse to share with all of you. If your printer is in need of a guardian or mascot, this one might just be for you. No, I really am not sponsored by E3D but their products really are top-notch and if you are in the market for extruder or hot-end parts, please consider going to their web site: http://e3d-online.com. Peace and God Bless.
