Screwdriver

thingiverse

A versatile screwdriver with a rotating palm rest feature. This design utilizes a 4x4x11mm magnet to securely hold the bit in place, but if you don't have access to a magnet of this size, you can use glue for a more permanent assembly. For optimal results, I recommend printing at least two perimeters and using solid 100% infill or a high perimeter count on the endcap. After four years of daily use, I'm extremely satisfied with the look and feel of this design. If you have a magnet that you'd like to use, please let me know its size and I'll modify it for you. 2-7-20: A slightly longer version of the screwdriver was uploaded to provide better grip on the bit. 2-7-20: Additional ribs were added to the end cap to prevent it from unscrewing itself. 1-8-18: The old version of the swivel end cap was removed. 1-8-18: A new version that can hold a hex key and stem parts was added, thanks to Andrux51 for suggesting this idea. 3-15-16: A version without the palm rest swivel end cap was included. 3-16-16: A V2 version with a screw-on two-part end cap was added, which is less prone to breakage.
