Description

This fully 3D printable ukulele (save for bolts and strings) uses an acoustic transducer to carry the lower frequency sound created by the strings to a very thin membrane on the bottom of the body. The sound is focused and projected out of channels in the body to (hopefully) create a fuller tone with reasonable amplitude.

I am still working on the design of the head and tuners. Right now, to have a good gear ratio for the prototype, I made the gears almost comically large.

UPDATE!!
I'm refining the design of the geared tuner head but I wanted to test the tonality to see if I was getting somewhere so I quickly designed a test friction head and tuning knobs to try it out.

I have uploaded all the current parts for everyone to TEST this EXPERIMENTAL design! Have fun!

A couple of notes: I am tweaking the body design. The bridge is a little wonky and the transducer pops right off! I have to think that one over a bit. The bottom membrane is only two layers thin. It is tricky to print and even trickier to remove from the platform. BE SUPER-CAREFUL TO NOT TEAR THE MEMBRANE OFF!

The sound the first prototype makes is bright as expected but it is pretty loud. A good sign!

NOTE: This friction head is for testing only, it will no longer hold a tune after a while without shims or other "friction-enhancers." The geared tuner is the solution to this, I'm just working to make it a better, more reliable print.

Stay tuned!

So the new head stock and tuning pegs are in place? There are no more gears for the head? That will surely make this job easier! This is great work. Any chance you can give me the overall dimension for printing to he parts? Thanks for sharing this killer cool model.
Hi Erik,
I create a new version which based on your two amazing parts.
Thanks for your sharing!
Have a look, please.

Hey guys, great job here!
I'm just curious what's the total weight of printed model?

Hi - Just a friendly inquiry about the status of your gear head. I printed the whole thing, except for that part, since, I knew it was obsolete anyway. The print came out fantastic. I'm just waiting on the new head since it seemed like a waste to print it when I knew it would get tossed away soon, anyway.

Fantastic work, btw!

what settings has anyone had success with, I would rather not waste that much filament by doing to much or little infill , or trying to do it without supports.
Mine started dripping during printing. Do I need support structures? I was using PLA...
I printed it with support, but now there's support inside of the uke. i don't think it'll play :(
Great design looking for geared head

Hey Erik,

Awesome job with this, hope to see the geared tuner up soon!
I'm new to 3D printing. Just built a Bukobot with an 8 inch build platform. How much build space does this require?
I think you will be ok. Its in 3 parts I beleive.
Cool! Thanks. I made it 90% scale, just in case. And it looks a lil small. So you were right!
What type is it? Soprano, concert, tenor or baritone?
Definitely a soprano uke (in terms of scale length & fret spacing). Although you could probably scale it up if you had the build volume to print a larger uke.
what settings to print it with?
Have you any information regarding printing using ceramic materials?
This is quite fun! Do you have any updates?

What did you model it in?
need support printing?
disqus.com/thingiverse-e16ff47e6c201e7636a5325e01185656/ you should try to tapper the friction knobs and holes like on a violin. They would probably stick better then.
Nice thing. Do you have the dimensions of all the parts ? It's a missing information in many thing, and it's cool to see if it sit on our printer befor downloading all the parts. Thanks.
 So, i check, you must have a printer who can do 220mm things.
Amazing! Thank you very much for developing this cant wait for your final version! I love music :)
how did you bolt everything together? did you make your own bolts?
I just used spare bolts from my MakerBot projects.
How are things going? Did you get your Replicator 2? Did you get your body printed out? Do you have a fret-board design ready?
I did get my Rep 2!  I printed the body the neck and as I was printing the head, it started jamming.  I'm getting some projects done with my job right now, but hopefully at the end of this week, I will have the head and tuners printed and strung.  Then I will upload the rest of this guy.

Thanks!
Eric, Please let me know how it goes! Can you post a quick video of you playing the uke when you have it completed? I can't wait to make my own!
First test is done.  Test parts are uploaded!  Have at it!
Acheivement unlocked! It sounds great!
Is it possible that you participate in the project with your interview?
I am looking forward to hearing from your soon.
Hello Mr. Rosenburgh, 

My name is Rodrigue Guidigansou and I´m Master student at the University of Paderborn in Germany. 

At the moment I´m working on a project in the field of innovation management targeting 3D HOME PRINTING. I´m a great admirer of your post and I´m wondering, if you are interested in sharing some of your ideas and expriences with regard to this field with me and my team. 
Therefore I would appreciate it, if you agreed to a short interwiew (about 10 minutes) via skype/ thingiverse forum/ or whatever you feel comfortable with.
I am especially interested in gathering information about printing Household goods and musical instruments.
Your answers will be used with anonymity and only at university.

I am looking forwaerd to hearing from your soon.

How does the print bed need to be to print this?
Hey, cool looking work. Make sure you have enough of a I closed sound box to get the instrument's main resonance, the fundemental low enough to have the Ike produce some bass frequencies. If you don't have enough of a box you'll. get loud trebles, but nothing else.... Good luck and get one made!
Certainly worth a shot with ABS too. I'm intrigued to see this come together! Good design.
What are you using to render you images ?
 
I am using Autodesk 3D Studio MAX.
