Ninja-Drillpress-Skills Produced This Glow Plug Extruder


Still looking to make your own 3D printer? Don’t have many tools or a big budget? Well, [Adam Kemp] has just the hack for you — a DIY extruder that can be made with only a drill press and a few hand tools.

First, a little background. [Adam] loves the nitty gritty side of 3D printing, so he’s managed to build his own printer almost completely out of recycled parts from printers, scanners, etc. Unfortunately, there’s not much of an option when it comes to the extruder. Almost all designs online feature 3D printed parts. Not wanting to admit defeat, he came up with this clever glow plug extruder design.

As you can imagine, it requires a lot of drilling, and it would be a heck of a lot easier on a mill — but that’s not the point here. He even goes into detail on how to hob the extruder feed wheel using nothing but a tap, a drill press, some skateboard bearings, and a few washers and nuts. The entire guide is great, so if you want to feel like MacGyver for a few hours and you need a good extruder, try it out! 

To see the extruder in action, stick around after the break.
