Kerf Maker

thingiverse

This design is based on the design of a similar jig posted by Shop Built on YouTube. The video was excellent, but it would have been more helpful if he hadn't had it running at such a fast pace, making it difficult to see exactly what he was doing. Despite this, I recognized that this project would be challenging as a woodworking endeavor, but it was begging to be adapted for 3D printing. I'm attempting this project for the first time using my Lulzbot TAZ 6 3D printer. The parts are prototypes, printed with the "High Speed" setting in Cura software. I used 1.75 mm True Black Polylite PDA filament by accident and discovered that it works with my printer, along with the TAZ 5 using a hexagon hot end, by following these steps: use the profile for Polylite PDA or another filament type and switch to 1.75 mm in the advanced settings. A kerf maker is a tool used to make precise cuts in wood; you can skip ahead to the 4:30 mark if you're not interested in seeing it made from wood at this point (https://www.youtube.com/watch?v=YsfOWa_TFR8&t=173s). I purchased knurled low-profile thumb nuts from McMaster Carr (https://www.mcmaster.com/#92815A115). The threaded parts are 1/4-20 x 1/2" long and 14-20 x 1" long; I couldn't find a set screw that long, so I modified a bolt to work.
