3D Printed Dremel Arrow Saw

Introduction: 3D Printed Dremel Arrow Saw

3D Printed Dremel Arrow Saw Summary

Here are instructions on how to make an adjustable arrow saw that allows for custom arrow lengths and consistent cuts. This is a simple build that includes 3D part files for printing. The use of extruded aluminum rails allows for easy adjustability for arrow length and stable mounting points for the 3D printed parts. There are improvements that can be made to this design but it works well for what I need it to do! I hope you will enjoy making your own.

Step 1: Materials Needed

Note: There are cheaper options for each one of the links posted. These links will give you all the information needed to purchase or to find cheaper alternatives.

Step 2: 3D Print Your Parts

I used the Creality Ender 3 3D printer with PLA material for this project. STL files for printing are attached.

  • Arrow Rest - Allows you to hold the arrow shaft in a stable position next to the cutting wheel. This is my original design.
  • Arrow Stop - Allows for consistent arrow lengths when cutting multiple arrows to size. The offset hole in this part lines up arrow shafts with the edge of the cutting wheel. The hole is 9mm diameter which fits most arrows. Certain arrow shafts will be too thick for this hole size. This is my original design.
  • Dremel Holder - I took an existing design from Nikus and then changed the design to mount to Extruded aluminum rails. Thanks for the great original design Nikus!
  • Dremel Clamp - Clamp to hold the Dremel tight to the Dremel Holder. The clamp does get in the way of the power button, so this can be improved. I recommend using a power strip switch to operate the Dremel. This is my original design.

Step 3: Assemble the Parts and Start Cutting Arrows!

Assemble all the parts and you are all set. You can see that I incorporated this arrow cutter into my extruded aluminum workbench. You will need to find a way to mount your extruded aluminum profile. There are many ways of accomplishing this. One of the easiest ways to mount the extruded aluminum profile is to attach 2 x right angle brackets and mount it to the edge of a table.

When cutting arrows, make sure to cut one side and then twist until the complete shaft is cut. Do not cut by pushing the shaft through. Always cut with a twisting motion for an even cut.

I hope you will enjoy using this arrow cutting system so that you can get outdoors with your bow and shoot some arrows!

Note of Caution:

When cutting carbon arrows have a vacuum placed near the Dremel cutting wheel to suck up all the dust as you cut arrows. It is hazardous to breathe in the dust from cutting carbon arrow shafts. I have seen a few designs incorporate a vacuum hose clamp next to the Dremel cut-off wheel.

    Hey, nice. It's great to see the application of Nikus's initial design. Very slick!
