Hobber Tool for RepRap Extruder Bolt with Dremel

thingiverse

I purchased a Proxxon Table Kt for my Dremmel: http://www.amazon.com/gp/product/B000S81MHY/ref=oh_o02_s00_i01_details, which I used to create a tool that manufactures hobbed bolts for RepRap printer extruders. To use this tool, attach it to your Proxxon Table Kt or equivalent device and ensure the height is aligned with the center of the bolt before cutting. Be cautious not to cut too many at once as the bolt can become quite hot; I recommend cutting a maximum of three bolts before allowing them to cool down. For optimal results, make the tool from ABS rather than PLA due to heat concerns.
