Hold 3 bits per side of your drill by attaching these to the screw hole where the belt clip can be attached. I used M3 x 10 screw to hold it on.
PETG seems to work the best. Rotate the thing to put the flat side on the bed. Put a support in the gap that wraps around the air vents on the drill. See attached screenshot from Cura to see what I'm talking about.
