Changes in v.0.0.1

Loosened up the tolerances a bit.

Added printable pins

Holes to squares

This is the initial release, and is not yet complete. I am starting with the gauntlet, and will move to the palm and fingers as the design gels. I am using the Raptor, and Beast hands as my study subjects, and many of my improvements will address the areas where those designs fall short.

The primary design goals of this prosthetic hand are:

1. Excellent Printability, without rafts, brims, or supports. All of these structures are built in as needed in each part. The goal to is to print right the first time, every time, on any printer.

2. Faster to print. Part size is kept to a minimum, both for comfort, and material cost savings, without sacrificing durability.

3. Stronger joints. All circular joints are oriented to be printed on their side. This produces a stronger joint, that is less likely to split during assembly, or rough use.

4. Good looking. Hey, it's gotta look good, right?

Materials and methods

Any hardware like screws will be metric.



Issues are used to track todos, bugs or requests. To get started, you could create an issue.

Dear friends from the e-Nable community!

We've created an assembly viewer for YouMagine which allows you to show a design fully assembled in the 3D view on the design page. This was design specifically so people can share complex designs and still show the relationship between the files and where the printed parts need to go into the assembly. An example is this design:

Make sure you also click on the Bill of Materials entry inside the 3D view. You can then see the objects in 3D and the lines that refer to files are actually linked. You can also include and reference non-printable files and indicate that they're not printable (a checkbox). This will become really useful as we integrate useful tools that help people who are printing lots of small objects and who want to keep track of what they have and/or haven't printed. You can go into "edit mode" and start creating an assembly in the second step. Feel free to let us know what you think about this feature! We'd love to improve on it!

Printed on:
Da Vinci 1.0
I printed with 0.2 layer height the results seem pretty good not sure what tolerances you have the bars/holes designed for but my print required a large amount of sanding. Can't wait to see the next version. I forgot to mention it took me about 1 hour 45 minutes to print this on my relatively slow printer. I think this is an excellent start to what will probably be an amazing design.
