I found this great handle http://www.thingiverse.com/thing:129760 for hex wrenches. However it was for only one size. I've create a customizable version so you can create your own for different size keys.


The best approach is to use the customizer, although you can download one of the STL files if it matches the size of your key.

To use the customizer, measure the width of the key, when rotated so it's the widest (as shown in the photo with the digital calipers). Enter this number as the diameter for the hole.

By default, the slot is increased in size by 0.15mm to compensate for differences in printing. You can adjust this to make it looser or tighter.

You can also change the diameter of the handle. I prefer the 25mm size that is the default.

You should really put a height customizer in the thingiverse Customizer app. It's ALREADY in the scad file. Would be almost no issue to do, and would probably be a lot better for other people. I've checked, and already made a little stubby one to save time and plastic.
Anyway, thanks for the design!

Neat, was struggling with a fiddly allen head screw and thought about making my own, but figured I should search first.

I wonder though if a slight re-design that uses a screw to hold the allen wrench in place wouldn't be a good idea, can re-use screws, would chew through less zipties.

Printed at 10% in XT, works great!

very nice thing thanks

Thank you for posting this, works great!!! i love it

It looks pritty handy

We don't have digital calipers but I think we have the manual version.

Capable of taking a lot of force? Great job! Andrew (http://3dhacker.com3dhacker.com)

Is there an option for lettering in the customizer? It a MUST

Pro tip, if you measure the flat sides on a hexagon and multiply it by 1.155 you get the diameter needed ;)

Printed out great using Slic3r an i3 and ABS! Agree with others about
alternate locking of any sort. At the very minimum I would say increase
the thickness of the thinnest part of the slots for the zip ties. One
slot broke on the very first insertion. Doesn't really affect
functionality from what I can tell though.

A thick locking plastic C-Clip lock that rotates around the handle would make this perfect.

Would be better with a proper locking mechanism that makes it easy to insert/remove the key.

I'm thinking maybe a gun bolt-action idea with a bump on a tab that the short end of the wrench snaps into, or something to that effect.

Where? What does it shoot?

Any chance you could design a handle for xilte tools. The hex handle could work with a little modification.
Thanks in advance

Can you provide more information? What are xilte tools?

Likely Xcelite was intended..

amazing thing , thank you this is great tool
