A hand for a child

No problem, and best of luck!

Beautiful3D · 2016-07-08T18:35:51.000Z

Best of luck with your goal and sorry I can’t help.

It’s a beautiful thing you’re doing!

kr0sh1 · 2016-07-09T12:12:40.000Z

I don’t know if anyone has mentioned the e-Nable project yet, but that’s where I’d go for designs, should be several makers in the area on their list who can replicate one for you.

kr0sh1 · 2016-07-09T13:11:00.000Z

Ah that actually is enablingthefuture! Need a chapter down here in Plymouth, lots of servicemen and women who’ve lost limbs. Anyone keen to form a chapter?

zounobody · 2016-07-09T13:40:20.000Z

Hi, Thank you for answering. I have aleady asked them and sent them the pictures and built the form. Am waiting, there is too many people in the queue… Regards, Zoubir

kr0sh1 · 2016-07-10T12:18:44.000Z

So what’s the ‘form’ then, an insert inside the prosthetic? Was it ‘Team Unlimbited’ you contacted, because it might be that they just need someone to sort out the CAD design side of things, I’d be happy to facilitate.

Hi,

As I did not get any news from you, am wondering whether you forgot me

Thanks

Zoubir

Hi,

Thank you again for answering.

In the Enable form, they ask to push some personal information and 3 pictures about the hand. So, this is why they decided that the model will be more “Phoenix” instead of “Raptor”. which make the task more complicated. My understanding :

My nephew hand is missing enough inflection and this is why the hand design must include the forearm. So, the design must more go for a “Phoenix/Unlimbited” than a “Raptor”.

Thank you in advance for your help.

Regards,

Zoubir

Hi Zoubir,

we are using the models of “enabling the future”. The necessary steps are to chose the right model (wrist oder elbow powered) and to get the right measurements for the size of the model. The adjustment will be done by scaling the model of enabling. If you provide us further informations we could check the possibilities.

Best regards,

Robert

Hi Robert,

Thanks a lot for answering.

Please let me know what you need to build the right adjustement.

You can find enclosed 3 pictures asked by Enable. You can see the measurements. And please don’t hesitate to ask if you need more information.

Thanks again.

Regards,

Zoubir

Hi Zoubir, you have a great cause and looking for a solution makes you a really great uncle. You’re in the right place to get help, and thank you for letting us know enable queue is backlogged, they should see an influx of people with printers signing up having read this.

You mentioned costs - nobody seems to have really covered that.

The hubs have various reasons for being here, Profit isnt always one of them, and whilst everyone has costs to cover, I would like to think nobody here would charge you anything for a project like this. To give you an idea of raw material cost, Plastic is usually priced per Kilogram, and the cheapest materials are PLA and ABS, and good quality PLA sells around €20-€50 per kg. Its also rather unlikely your nephew would require a 1kg hand. The only variables are the printers time and energy costs. I’d like to think these would all be waived to help your nephew.

Something else nobody mentioned yet - as your nephew grows the arm will need to grow too, requiring parts to be periodically replaced with bigger ones. I don’t know how frequently this qould happen, it mainly depends on your nephew!

Are you clear on your next steps, and do you have someone identified to help you print this?

Good luck to you and your nephew and please keep us posted.

zounobody · 2016-07-12T21:31:33.000Z

Hi Chris,

Thank you so much for taking time to answer me. I really appreciate.

All the aspects you’ve pointed out are right and the developpment of my nephew hand is one of them. I expect to ask for new printed hand till he stops growing. Then, I will look for a permanent chirurgical solution option.

But meanwhile, I really need to achieve the 3D part. My request is still in the Enable queue and I have no idea when or where the project will start, there is no visibility about the request and I understand this, since it is a volunteer organization.

So, regarding your last question, I unfortunatly have no one identified to help. I also contacted some “private” organization but none is answering. I would really be happy to help about the total cost required to realize it, but first I need someone to help.

I also got in touch with a guy from Handesign, he was ready to do it, but then realized that he can only make a Raptor design not a Phoenix one.

I also contacted “Open Bionics” via their contact form, but they don’t answer.

I keep hope (L’espoir fait vivre )

Thank you again and best regards.

Zoubir,

I’ve been looking over the e-nable site over the last few days, and have decided I would like to help you with this especially since you’re having so much difficulty finding someone locally to do it for/with you. I’ll preface this by saying my team and I have never done a prosthetic in the past, but I am a mechanical engineer and have very strong modeling/design skills. We do a fair number of complex mechanical models both for our day jobs and at home, so as long as you’re a bit patient while we learn the ins and outs of these designs, we can definitely help you out.

Shoot me an email at hubs@enza3d.com and we’ll talk more about getting this done and what we need to get started!

zounobody · 2016-07-13T16:05:14.000Z

Hi,

Am very happy to read your answer. Finally some hope!

Regarding your previous message about french universities, I’ve contacted ENS and EcoleCentrale, without any success.

Am on my way to write to you on the email address you mentioned.

Again thank you for lighting the candle.

Best regard,

Zoubir

Futurefabbers · 2016-07-14T10:19:18.000Z

Bonjour Zoubir,

please drop us an email to info@futurefabbers.com. We will be happy to give you some additional information which need to be considered. 3DHubs is a

commercial platform. They get for a provision for any part having ordered via 3DHubs. Something else and very important which I would like to point out:
A 3D printed hand is a medical device. In Europe these devices may only be produced by following given laws and regulations. Most importantly is that medical devices may only be distributed by medical experts. However there are possibilities to provide you that hand. Therefore please drop us an direct email.

a bientot

Özlem

kr0sh1 · 2016-07-14T12:15:56.000Z

So you think the government would prevent the sale of the print due to it being medical in nature? The purpose of a print is not technically defined by 3DHubs so surely they’d be exempt from any liability or bureaucracy?

Perry_1 · 2016-07-14T12:58:47.000Z

Zoubir, Join the enabling the future google+ circle. Tell them you need help, folks will jump on. I reiterate that It is best to get someone locally involved, perhaps add the /paris tag here.

Perhaps contact filemon to get this added to the /paris group

Enzou3d,

I see you are in New York. But if you are up for it, here is the direction to proceed.

OK, start here.

Contact enablingthefuture, and tell them you want to build the hand for Zoubir. You can also do this in the google+ circle.

Then, read this------

Yep it is not allowed to sell a medical device unless you have received the permission to do so. If somebody sells without, he/she is liable for any damage in any case. Exempt from given regulation is a “prescribed” device for a given patient. We are therefore just checkin once again 3DHubs terms, but I don’t expect them having taking such request into account.

Perry_1 · 2016-07-14T13:18:42.000Z

Just do it outside of 3dhubs if you are worried.

Upvote for giving clear instructions on how to go from A to B on an eNable prosthetic.
