Application for help

June 26, 2016

Our prosthetic designs are, and we plan for them to always be – free and open-source.  You may use, build, share, and modify them.  Please just promise to share back your improvements, and do not make profit from them, beyond cost of time and materials.

If you have the means to get started on the endeavor of making one for your self or someone else, please do – and let us know how we can help!

If you need someone to build one for you, let us know.  We maintain a queue of requests, and build fingers for those who need them on a best effort basis.  We haven’t yet established a set price for building our finger prosthetics for others, as we wouldn’t feel right charging as much as our time would cost.  However we do accept donations. If we’ve helped you, or you’d like to assist us in continuing to help others, consider making a donation.

You may also consider reaching out to, where they help match people in need, to those with the ability to help

If you’re interested in having us build a unit for you, please fill this form.

Please note!   We are not doctors, and are not a medical company.  We do not create medical devices, or give medical advice.  We simply offer DIY prosthetic designs for novelty use, along with varying levels of advice and support in helping folks create them.


Fields marked with an * are required

Use this form to submit an application for a finger prosthetic.  We currently build them on a best-effort basis, as time permits (we have day jobs!).  We do not have a set price, but encourage donations to help us keep operations running.

Please read the measurement guide for instructions on how to determine these values.
