I present the base section of my two or three piece bicycle tool set.
15mm open ended pedal spanner,
1/4" hex bit driver,
5mm hex driver,
1/4" square driver,
Flat driver 5.5 x 1mm,
Phillips driver No.2,
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.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page
