A small HEX 1/4" / 6,35 mm bit holder you can carry in your pocket or keep in your 3D printer's toolbox. :)
This pocket bit drive (sometimes called bit holder) can be used with HEX ¼" (6,35 mm) BITS directly or with adaptators like HEX ¼ to SQUARE ¼", etc.
This model was designed so the BITS stays firmly in place but can still be removed without using a tool. Be carefull about the material shrinking if you print it with other material than PLA/PLA+/PLA-HD.
There is also a hole at the back (top) of the tool where you can, optionnally, place a circular magnet that will holds the BIT in place. The hole has a diameter of 10 mm and a depth of 3 mm so can use 10x3 mm, 10x2 mm or 10x1 mm magnets.
If you plan to use this tool in contact with hot parts, for example if you want to use it to unscrew a 3D printer's nozzle, you might want to print it in a material that is less sensible to heat than PLA. You should try ASA or PETG.
How to build it?
To print the different models I used PLA+ from eSun and Creality.
Because the model has a rounded bevel on its base, you should switch off cooling completly for the first 8 layers in order to prevent warping.
I printed it at 60 mm/s on a Kossel delta 3D printer with a 0.4 mm nozzle and a layer size of 0.2 mm. I used rectlinear Infill with a density of 25%. No support required so i didn't add any
Assembly
If you printed the magnetic version, you can add a 10 mm magnet at the top of the tool. The magnet should be press fixed into the tool so use a pliers to accomplish this.
That's all, you can just use ¼" HEX BITS with the tool. :)
