Update: Increased bit hex hole for better bit fitment. Added small tabs to Bit Retention Sleeve to help hold it in place.

Printed using Bambu X1C and Printed the Loose version on a Ender 3. Print the body using PLA+ with 4 walls for strength around bit area, infill percent and pattern doesn't really matter.
The internal overhang angles are 60 degrees, do not use supports. Print setting should be “Low and Slow.” On my Ender I printed at around 45mm/s and at the bottom temperature range for PLA+
The arrow facing you is the direction of force, simply move the bit to the opposite side to change directions.
