This simple practical print slides onto telescoping hex-shaft bit-drivers so that you can more quickly start/tighten screws, bolts, or nuts before switching to a ratcheting handle. Originally designed for the Harbor Freight T-handle Bit Driver (https://www.harborfreight.com/t-handle-ratcheting-screwdriver-61727.html), but should work with any similar ratcheting driver handle.
Modeled with 0.15mm clearance around hex shaft.
