Trumpet Adapter Redesign - King Cleveland 600 Trumpet

I designed the first iteration of the King Cleveland 600 Trumpet adapter. I took the files from the Bach student trumpet and slightly modified the height and location of the holes for the tubes to extend out, based on a couple photos that were sent to me from a family that is interested in an adapter for their son. I'm going to send a test print to the family to see how it fits on the trumpet, and then make any necessary revisions.

e-NABLE Fellowship - Karuna's Trumpet Holder on Filamentix

Another really great write up about the Trumpet Adaptive Device on Filamentix. 

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 - Rendered in Keyshot

I am rendering a few images for my portfolio and thought I would share... Oh, Keyshot, you are fabulous. 

I couldn't resist rendering one image in a metallic finish. 

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!

All of the parts

Palm and gauntlet with dovetail for adapting to trumpet holder. 

The orange piece (main) goes on first...

Followed by the black piece (bottom).

 Ta-da! 

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 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?
