the Makerlele - MK1 by ErikJDurwoodII Nov 12, 2012

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!

VIDEO: youtu.be/4xRkysNNRc4

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.

RealityInc on May 31, 2013 said:

Mine started dripping during printing. Do I need support structures? I was using PLA...

RealityInc on Jun 23, 2013 said:

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!

RealityInc on Apr 28, 2013 said:

I'm new to 3D printing. Just built a Bukobot with an 8 inch build platform. How much build space does this require?

thecrazy on Apr 30, 2013 said:

I think you will be ok. Its in 3 parts I beleive.

ajks1018 on Apr 2, 2013 said:

What type is it? Soprano, concert, tenor or baritone?

bradkenney on May 20, 2013 said:

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?

mhedges on Jan 28, 2013 said:

Have you any information regarding printing using ceramic materials?

laird on Jan 21, 2013 said:

This is quite fun! Do you have any updates?

What did you model it in?

hyppyayo on Dec 31, 2012 said:

need support printing?

thecrazy on Dec 28, 2012 said:

ErikJDurwoodII you should try to tapper the friction knobs and holes like on a violin. They would probably stick better then.

Wapata on Dec 16, 2012 said:

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.

Wapata on Dec 17, 2012 said:

 So, i check, you must have a printer who can do 220mm things.

thecrazy on Dec 14, 2012 said:

Amazing! Thank you very much for developing this cant wait for your final version! I love music :)

aaronwro on Dec 13, 2012 said:

how did you bolt everything together? did you make your own bolts?

ErikJDurwoodII on Dec 13, 2012 said:

I just used spare bolts from my MakerBot projects.

aaronwro on Dec 10, 2012 said:

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?

ErikJDurwoodII on Dec 10, 2012 said:

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!

Is it possible that you participate in the project with your interview?
I am looking forward to hearing from your soon.

guiderorus on Dec 1, 2012 said:

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?

1oldclown on Nov 14, 2012 said:

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!

Bradpokey on Nov 13, 2012 said:

Certainly worth a shot with ABS too. I'm intrigued to see this come together! Good design.
