prosthetic hand: milwaukee prt.8 (materials and resources)

I've been quiet with my posts about Shea's hand. I'm not sure why as I have been doing a lot to prepare for our next meeting. I've been keeping up with all of the activity and collaboration occurring on the e-NABLE group. I'll have more info. on that soon. I ordered supplies for us to use in the creation of Shea's hands. I sourced most of this from Amazon, but many of the orthoplastic sheets were shipped from Patterson Medical, who apparently has an office just a few miles North of me in Cedarburg. My colleague, Adream called them, and they put us in touch with a regional representative who knows a ton about splinting, so this should create a positive relationship that we can use as a resource. I purchased cabling supplies, Velcro, colored thermoplastics, filaments (in Shea's favorite colors),  and splinting sock liners. Adream and I played with milling and laser cutting the thermoplastic to see if we could cut some patterns into the material. My laser cutter settings were a bit too hot, but I slices like butter; same with the milling machine. It does leave some burrs along the edge similar to when you machine nylon, but nothing that can't be cleaned up.

In the last few weeks I have been preparing links to where I sourced many of the materials for Shea's hands. During this time, Jen Owen was working on a new site for the e-NABLE group and she put out a call for resources for all things pertaining to 3D printed prosthetic design and creation. I put together the following and she now has all of this on the e-NABLE group's new website. You can access the e-NABLE site here.

Here is what I submitted to her:
