I present my one-piece driver/spanner tool with a variety of different driver points:
6.5 x 1.2mm flat driver,
No.2 posidriv driver,
5mm hex driver,
4mm hex driver,
T25 torx driver,
1/4" hex bit driver,
13mm socket spanner.
An o-ring is required to complete the assembly to help hold a 1/4" square drive socket on the square post (5mm ID, 1mm diameter, not included).
This model is designed to be printed in Stainless Steel or one of it's variants.
Although all care has been taken to ensure this model is correctly sized, due to variations in the printing process, some filing may be required to ensure correct fitment of some of the drivers and/or spanners.
The tool can easily be secured to a keychain or lanyard with a 10mm split ring or a No.2 McGizmo clip or similar 25mm gate clip using the hole in the flat driver.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page.
