I present the T-Bar hex bit driver tool, a commissioned piece for JLara.
It's features include:
A prying tip,
An in-line 1/4" hex bit driver,
4 more 1/4" wrench or hex bit drive points,
Various other wrench sizes:
Storage space for two 25mm long 1/4" hex bits in the handle and two more in the central cut-out, depending on the type of driver tip,
And a bottle opener (which has been redesigned, to improve it's function).
This tool requires nine o-rings, in two different sizes to secure various hex bits in place:
Two to retain a hex bit into the in-line driver at the prying end (9mm ID, 2.5mm diameter, not included).
Four to secure the two hex bits into the storage slots (6mm ID, 2mm diameter, not included).
Three more to hold another two hex bits into the central cut-out (9mm ID, 2.5mm 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 hexes.
The T-Bar can be secured to a keychain or lanyard with a No.2 McGizmo clip, similar 25mm gate clip or small split ring through the 3/8" hex hole at the top of the tool.
