Flex Bit Holder

thingiverse

A storage container for standard 1/4 inch screwdriver bits, designed to be printed from flexible filament, holds them securely in place. The bits can be easily inserted and removed, thanks to the flexible nature of the holder that retains them firmly. The container comes in four sizes: 4, 6, 8, and 10 slots wide, each holding 7, 11, 15, and 19 bits respectively. Flexible filament can be prone to stringing, producing strings, blobs, and zits that can spoil an object like this by filling the slots with hard-to-remove debris. To prevent this, the holder is specifically designed to be printed in "vase mode," where the printer's tool path simply outlines the perimeter of the object without infill. This eliminates stops and starts, retractions, and travel moves across open areas, allowing the print head to spiral smoothly around the object while moving continuously upwards. The result is extremely clean prints, as shown in the photos, with no post-processing cleanup or photo touch-up required. These are the actual prints produced by a Prusa i3 MK2 printer with NinjaFlex "Lava" filament.
