Flex Bit Holder

A holder for standard 1/4 inch screwdriver bits. Designed to be printed from flexible filament. The bits can be inserted and removed easily, and the flexible nature of the holder keeps them retained.

There are four sizes, 4, 6, 8 and 10 slots wide, holding 7, 11, 15 and 19 bits each respectively.

Flexible filament can be very stringy, easily producing strings, blobs and zits. This would spoil an object like this by filling the slots with hard-to-remove detritus.

For this reason the holder is specially designed to be printed in "vase mode", where the printer tool path just outlines the perimeter of the object, with no infill. In this mode there are no stops and starts, no retractions, and no travel moves across open areas, the print head just spirals around the object moving smoothly and continuously upwards. This results in the extremely clean prints shown in the photos. There was no post processing clean up of these prints, and no touch up of the photos. This is how it comes of the printer with the right settings.

The samples in the photos were printed with NinjaFlex "Lava" on a Prusa i3 MK2.

Print Settings

Notes:

Print at 0.2mm layer height, in "vase mode", with five bottom layers, zero top layers, and one perimeter. No infill. No raft or brim. When you slice the model for printing check that the tool path preview looks like that in the screenshot before you print.

Print slowly to ensure good adhesion between the perimeters.
