3D Print Parts

Printer

A Bambu Carbon X1 was used to print the files for the original hand using the recommended print settings.

1. Download and Print parts

Naming Schema of Parts

The middle, index, and ring fingers all use the same parts: Finger Joint 1, Finger Joint 2, and Finger Joint 3.

Joints are numbered from the base up, so joint 1 is the bottom joint and the fingertip is 3.

The part names are the same as the file names.

You can download the files from this site or the Onshape Document.

Zip file with all files.

2. Check Tolerancing

All Finger Joints

The dowel holes may warp during printing, so check that the dowels can fit into the holes (do not push too hard as it may crack the 3D print).

INSERT IMG

These outer dowel holes should fit the dowel loosely.

INSERT IMG

The inner dowel holes should fit more snuggly, but should not take a lot of effort to press in.

Using a drill and a bit (approx. 2.6mm diameter) drill out the hole to adjust the tolerancing if it is off.
