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 Fellowship - Karuna's Trumpet Holder - Printing Experiments Conclude....

The head print worked! Much faster than the side print and less clean up. 

Side print also worked on the first try - but it was a lot harder to clean up. 

And something else happened today --- that moment you become conscious of your unconscious decisions.... I look just like my office.

e-NABLE Fellowship - Karuna's Trumpet Holder - Hand Progress - Part 7

I finished the interlocking (v4) of the hand/palm today. These pieces will hopefully fit snug enough together to stay put, or could be permanently secured together with an adhesive. 

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.

e-NABLE Fellowship - Karuna's Trumpet Holder - Palm v2

I worked on v2 of the palm/hand today, got through this first iteration on the second design... I need to clean up the design a little bit, but I wanted to get something printed tonight, so I decided to send what I had finished to the printer before I left... I've got a lot of work to do on these parts still but I feel like I'm finally feeling the flow, so I'm confident it will all come together pretty quickly.

 I added an extra hole in the hand piece so that the user can adjust the angle at which the hand piece attaches to the trumpet holder... we'll see how it works!

e-NABLE Fellowship - Karuna's Trumpet Holder - Hand/Palm v2

I didn't get as much done today as I would've liked, but I did learn quite a bit about boolean operations. I started drawing hand/palm v2 for Karuna's Trumpet holder, but ran into a few problem right away with curve networks and boolean operations. 

After doing some research into why my design might not have been working, I decided to abandon the form and start over with less complicated curves for the palm... 
  I built this one the exact same way I built the previous, but before boolean-ing I went in and exploded all of the solids and deleted all of the flat surfaces that were "duplicates" on the seam. I'm not sure why this worked and the other way didn't - but it did - so I finally got a rough profile....

I'm currently working on designing the aesthetic surface and the functional parts of the palm... I'm going to keep working on this tomorrow.
