De-burring tool

Mine fell over on the table 3/4 the way up, so I'm including the file to print the top part that I drilled holes into the bottom and used epoxy glue to put them together. Between the holes drilled into the bottom of the top and the grid cross section that was left on thetop of the bottom, the glue is sure to hold it together.
I had to drill the main hole in the end with a 1/8" drill bit to get a good size as you want the de-burring bit to swivel. I also taped the side hole with a 6-32 tap to put in a screw from the side to hold the bit from falling out, but you don't want it so tight that it stops the bit from swiveling.


You can get the bits on Ebay or Amazon.
