I am brand new to this entire thing, but if I was going to dive in and try to make an arm for myself with the supplied files....how hard would it be to get this thing fabricated for a RIGHT arm as opposed to the supplied left?

Flipping to a right arm is not impossible. Though it is not trivial either. I would use Meshmixer. If you are comfortable with that application you should be ok. You might post on the e-nable google+ page or facebook page. There are likely instructions by someone for flipping other designs. The general concepts should be the same for any of the e-nable designs.

I happen to be putting finishing touches on a version 2.0 of this arm. That has a right hand version ready to go. I will be releasing a beta version soon. But, expect to have a release done by Thanksgiving.

Is there any Fusion source files you can share? This would help us all a lot! Thanks!

I just uploaded Fusion 360 files for two versions of the Arm and Cuff. The hand and fingers where done in Meshmixer so the STL is the best there is.

This looks very interesting. Nice job all round! I have a 15 yr old female recipient that could benefit, and I'm trying to determine the comparison between this and the unlimbited arm. What are the pros/cons that I should be looking at in making the decision?

Thanks JacquinBuchanan for your response.

The biggest difference is the more natural looking hand. There is also a whippletree in the hand allowing for a more adaptive grip. The thumb and fingers are on separate strings, and there is an adjustment CAM at the elbow for each allowing for different grip types.

I'm struggling to print the bolts. The threads are coming out very stringy. Any advice on settings?

Hi,
I am just wondering how you scale the arm to the recipients arm? I understand how to do it for an arm such as the Raptor Reloaded or the Cyborg Beast, but in this case, you print the arm flat. Can you guide me on how to scale it?
Thank you,
Jason

This is some fantastic documentation in addition to the design. VERY impressive. I'm curious if you'd tried to join the pieces together by basically "welding" them with a soldering iron? I've done this with a small flute print and have found it to be quite effective. Any thoughts?

Excelent work Jacquin, we look forward in e-nable Honduras to try out this Design! A cover will be awesome so we could personalize the device even more! What type of cord do you use for the stringing process, would you mind posting a link of it?

Very nice! I look forward to printing it. The men I have been building arms for in the Dominican Republic generally request a cover. I haven't looked at Christian's design but if it is an easily added thing, that would be great! Dean

Excellent job and I am excited to try this out. A cover would be great if you could provide one. I have a 14 yr old girl in mind for this. Can you post the dimensions so can work out the scaling down?

thanks
