SpinDriver - EDC Bearing Driver

🪛 SpinDriver – EDC Bearing Driver Overview The SpinDriver is designed for maintenance and adjustment tasks. It features a rear bearing that allows the body to rotate while the back end remains stationary and comfortably supported in the palm of your hand. This is a common solution in precision screwdrivers for 4 mm bits, but in this case it is adapted for standard 1/4-inch bits. The screwdriver integrates a 60 mm bit extension fully embedded inside the body, providing much greater strength and durability than designs where the bit or bit holder is only partially inserted into the printed part. Only a small portion of the extension protrudes at the front, keeping the design compact, robust, and highly functional. By adding a 1/4" to 4 mm bit adapter, you can use both bit sizes, making this an extremely versatile and compact driver—ideal for EDC maintenance tasks such as knives, watches, multitools, and other gear. 📐 Materials & Dimensions Required hardware 1 × 60 mm bit extension (1/4
