U-Joint Screwdriver Bit Adapter

For optimal results, print at a 50% fill rate and vertically with the thick side up; this method is suitable for low-torque applications. The bit performs well when used at angles below 20-30 degrees and is based on a customized universal joint. In future, I aim to find a stronger joint for higher torque. Note that assembly may need sanding due to tight tolerances.
