inner finger element

A freshly printed finger part. With my printer I do not get a perfect surface where the counterpart will move over when bending the finger. So I give a filing to to the surface to make it a bit smoother.

Drill the hole

I use a 3 mm drill for the inner finger part. As you can see in the picture this might leave some material at the end points, get rid of these with a soft touch of a bigger drill.

Outer finger element

For the outer part I use a 2.8 mm drill (I got one with the Dremel drill set). With the smaller finger parts be carful when redrilling the hole and do not use too much power to avoid breaking the part.

The rotation axis

I use a piece of filament (2.85 mm) that is slightly longer then the outer diameter of the outer finger part. Make sure befor adding the axis that the two parts can freely moove inside each other and file the surfaces if not.

Pushing the axis in place

As the axis will have a tight sit in the holes of the outer finger part special care needs to be taken when pushing the axis through the holes. Use a good counterpart to avoid applying pressure to the narrow finger part. A nut below the hole could also be used when pressing the filament peace through the hole.

The connected parts

use a cutter to remove the overstanding axis parts

This still will leave extra material at the axis, so pick up your file again and get rid of the overhangs

At the end you will have an almost invisible axis that will stay in place. Of course using a different filament color can also be used to give your InMoov the individual touch you are looking for.
