Parametric Carbon Fiber Arrow Cutting Jig for 3d Printer Delta Arms

thingiverse

I needed to cut multiple carbon fiber arrows all the same length for a Delta Printer I am building. I decided on using a cutoff wheel on my rotary tool after discovering it is recommended by many users. Cutting just one arrow was relatively easy, so I made a jig parametric so I could quickly and accurately cut 6 carbon fiber arrows at once. If you do not use this method, the jig still allows you to cut multiple arrows all to the same length as precise as your measurement tools can be. It's likely that you will need to make two cuts on each arrow since getting a straight perpendicular cut using the cutoff wheel can be challenging unless you are almost at the end of the material. Your first pass doesn't have to be accurate, but the final cut does. I uploaded the parametric Openscad file allowing you to adjust 15 variables and three Stl files for an 8mm shaft diameter that is suitable for my printer build's arrow length. My actual arrows were only 7.5mm, so I decided on using a larger diameter of 8mm for testing purposes. The .stl files included allow for cutting just one arrow, perfect for testing cuts and settings as I did initially with an 8mm arrow bought from Walmart at a low price of $3.25, and is quite long at 31 inches. Presently, I'm designing a customized Delta-Six printer utilizing strong vertical 2060 V-slots measuring 1000 mm, coupled with bottom sections measuring 500 x 2020 mm (x2), and top section measuring 500 x 2040 mm to give me desired rod length of approximately 515 mm.
