Description

These hex (allen) key handles are inspired by the original 'Wiha PicoFinish' set.
I decided to add a turning cap with actual (3D printed) ball bearings for increased smoothness of operation.
See images for additional parts and a simple, 25-step, assembly guide.

I've included sizes for up to a 4mm hex key, bigger doesn't really make sense for this size handle.

Mine were printed in PLA, but (even) stronger materials might make more sense.

Finally, as of now I've still not cut off the excess (short) end of the end of the actual allen key, and as it turns out it's very practical to use for instance your index finger to apply extra torque when needed.

Note: as always, any stereo images are of the cross-eyed type.

printed okay but no idea as how to assemble it. parts don't seem to fit right so not usable for me.

I see on your bio that you have zero models and zero downloads etc. The provided images for assembly are pretty (self-) explanatory. So maybe it's just not for you.

@user_1927194589

my issue entirely. I did not realize that I needed to acquire the ball bearings. I mistakenly assumed everything would be printed but the bolts and nuts. It does appear to be a good model if I had the little balls. again, my issue and not the design.

@speeedydan

I've invested quite some time to make a detailed set of images with explanations of how to assemble. They should be clear enough to get a sense of whether something like this would be suitable for you.

Agreed, parts are small. Hopefully the images helped. Thanks for the great review !

@AndrewPolk

Replying to @speeedydan :

The images were most helpful. I wouldn't have been able to assemble them without them. Great print.

@NEoZOic_Rocks

I love the idea of it but it is a nightmare to put together. The ball bearings just don't want to play!

@speeedydan

The orientation of some of the parts is essential. Make sure no part is flipped or upside down.
