e-NABLE Fellowship - End Term Documentation


e-NABLE Fellowship – End Term Documentation



As a part of the 2015 Summer Fellowship Pilot Program of the Enable Community Foundation, I conducted research at the University of Wisconsin Milwaukee’s Digital Craft Research Lab into adaptive devices, hand design aesthetics, and alternative materials/processes for the creation of hands.



Week 1 - 8

  • Designed and prototyped adaptive technology for Bach Student Trumpet TR300. This includes; (1) a semi-permanent casing around left side and base of valves, (2) dovetail mechanism for attaching a scalable hand/palm design, (3) a rotational palm attachment and (4) a corresponding gauntlet with flexion and extension capabilities. During the design process the instrument’s existing aesthetic was considered and prioritized to ensure and maintain the integrity and elegance of experiencing a Bach instrument.
  • Rendered designs using Keyshot
  • Released designs as open source files, on youmagine.com and thingiverse.com



Week 9

  • Research, design and prototype alternative design methods for the creation of gauntlets Experimentation with thin-walled prints for flexibility.  


All of the research and design I conducted during the 2015 Summer Fellowship Pilot Program of the Enable Community Foundation, was documented on my personal blog; http://digitalfabricationanddesign.blogspot.com/ and will be shared during a Handathon building event at the Wisconsin Science Festival, October 24-25, 2015 in Madison, Wisconsin.

e-NABLE Fellowship - Karuna's Trumpet Holder - Final Design Release

...and that's a wrap! Like with anything I've ever made before, I feel like this is object is one I could keep designing forever, over and over, re-doing all of the components until it's perfect, but sometimes you've just got to say "Hey - this is great! 1st iteration done!" and take a break for a little while. I've had such a great time working on this project. I never could have anticipated the feeling of accomplishment associated with designing for the e-NABLE community. Thank you everyone who has made this fellowship possible!

You can find the final designs on Thingiverse and Youmagine.



e-NABLE Fellowship - Karuna's Trumpet Holder - Scalable .stl

As I am getting prepared to release the files, I've begun to create scalable versions of all the Trumpet Adaptive Device components. It's been kind of challenging for a few of the components because I hadn't thought about this being needed at first... so I haven't modified them in the "right" way, but they will work just fine. I will definitely keep this in mind in the future for any other scalable objects I make.

e-NABLE Fellowship - Karuna's Trumpet Holder - Final Revisions

Revised Gauntlet |||||| The functional parts of the gauntlet needed a little bit more attention, specifically strength. I attempted to extend the surface slightly to increase the amount of material around the hole, but it wasn't working right. I finally decided to simply adjust the location of the hole and also adjusted the size of the Velcro slot to be more in line with the stock size of the material. 




Revised Palm ||||||| I changed the placement of the holes for rotating the palm on the trumpet holder. The previous holes were estimations, but now the holes are custom to Karuna's liking.

S100 - UWM @ Morning Glory Fine Art Craft Fair

I was given the opprotunity to organize, curate and execute a juried alumni exhibition for the Morning Glory Fine Art Craft Fair (more info: wdcc.org), so OF COURSE I said yes. I've participated in craft fairs before, but I've never run a juried exhibition, so that is very exciting to me.

One thing that I really miss about participating in events with Studio303, is organizing and planning shows, and interacting with the community.

So far, I've created a call for entry, designed an exhibition postcard, created a website, helped design a display, and started fabricating display... and much more... Hope you stop by! August 8-9th 10AM - 5PM at the Marcus Center for the Performing Arts.


e-NABLE Fellowship - Karuna's Trumpet Holder - Prep for Karuna's Fitting

I finished up assembling the trumpet adaptive device, just in time for Karuna's fitting. I had about 15 minutes to snap a few quick shots before he arrived. 






It fits in the case!

 Ta-da! 

e-NABLE Fellowship - Karuna's Trumpet Holder - Assembling Parts for Fitting

View of my work station today.... Definitely the most "handwork" I've done so far on this project - it was great!

I added padding to the gauntlet and wove the Velcro through the slots, but left enough extra to make modifications for when Karuna comes to the DCRL for the fitting. 
Assembling the dovetail attachment. 
Karuna needed to take his trumpet back today, so I made sure to document the pieces on his trumpet really well so that I could have a few shots with the device in place. 
I realized during the documentation process that the holes for the angled mechanism were put on the wrong side - so I modified the piece for the fitting with Karuna by drilling a new hole. 


Our estimation was slightly off - The perfect angle for Karuna was right in the middle... I drilled this hole out and secured the Chicago screw tightly, so the device should work temporarily. We will be printing him a final version after a few minor tweaks to the design next week. 


e-NABLE Fellowhsip - Karuna's Trumpet Holder - Parts & Parts

Karuna is coming to the DCRL in a couple of days to try on the adaptive device to see if there needs to be further modifications for size. I've started piecing together a couple palm/gauntlet sets, so that he can have a few options for fit. This is the most recent pairing - most up to date with most modifications:
v1 of the palm, v4 of the dovetail and v2 of the gauntlet. I thought this was it - but it wasn't - I made the wrong size holes in the palm piece and it was also super thin and too flexible. 

v2.1 of palm, v4 dovetail, v2 gauntlet - when securing these pieces together I noticed that the gauntlet had to stretch pretty far to get around the thickened wrist part of the palm - so I am going to bend the attachment portion of the gauntlet to accommodate an easier fit. 


v3 of gauntlet - 4 holes for adjusting the angle of dovetail - above is in position 2. I still have to add some cushioning material on the inside, and will cut a few slots for Velcro. 






all of the iterations of all of the parts so far --- still more to go on the palm/hand - it is by far the most complicated component. Looking back, I have made so much progress this past month, and built so much skill in Rhino. I'm really pleased with how far I've come. I am excited to see what I'm able to accomplish in the next month as the fellowship wraps up.  

e-NABLE Fellowship - Karuna's Trumpet Holder - Palm v3

I spent most of today designing version 3 of the palm attachment. Frankie and I had talked about the potential to eliminate the Velcro on the palm attachment by making a cap for the back - like a socket. The challenge now is figuring out the best way to print this object on a Makerbot... (This leads me to think another iteration is necessary - version 4 will have two parts that interlock.) I am test printing two of these hand pieces currently - one printing on it's "head" and another printing on it's "back." ...Wish me luck!  
I created this top part the exact same way as the bottom - curve network & extruded surface & offset surface solids.



I borrowed wrist curve from gauntlet to create profile.




This profile reminds me of Darth Vader - HA! 


printing on it's head - with supports - probably will fail, but why not try? 

e-NABLE Fellowship - Karuna's Trumpet Holder - Palm v2.1 & v2.2

I modified the thickness of the hand/palm piece near the wrist/hinge. I'm trying out two different approaches - one in green and one in blue - the blue one is quite thicker than the green. I am still working with surface offsets to construct any modifications to my designs. I also modified the dovetail slot to have a few more holes to account for a couple more potential angles at which the hand  and arm can be positioned.
