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

I needed to cut some carbon fiber arrows to all the same length for a Delta Printer I am building. I did a test of cutting just one arrow using a cutoff wheel on my rotary tool, which seems to be the recommended way to do this. Since cutting the one was quite easy, I made the jig parametric so I could cut 6 carbon fiber arrows at once. I might use my CNC router to put the drill holes for mounting the jig on a piece of board. That way, I should be able to cut them all to quite an accurate len
