This 3D PRINTED UKULELE only costs $10 to MAKE! (but how does it sound?) 

The truss rod can help with the bend in thw neck. Truss rods were invented to counteract bowing of necks under the tension of the strings. So on traditional truss rods you can just ighten it some more and it eliminates the bend. However idk if this one works as well

my dad has built a wood ukulele before with the help of my brother, it looks and sounds beautiful, but it's really nice and he travels a lot and we wouldn't want to risk damaging it, so I might find a buddy with a 3D printer and buy a spool of wood PLA to try this build out! It might not be perfect, but if it broke in a suitcase it would be no big deal 😂

You need to go to a real hardware store. Metric has been a thing for a long time in the U.S.. There hasn't been a U.S. built vehicle that didn't have at least 50% metric fasteners since 1973. Also...the neck is bowed because you didn't bother to adjust the truss rod to correct the bow.

Right. Making Uks is the way to go. Some folks have tried to make violins. I think uks is a far better use of the technology, especially if you can produce a fairly good quality sound. I could imagine cranking out 10 for a high school group. You are on to something.

Thanks for the vid, I'm hoping to try one of these for my daughter.

Great job pronouncing Iz's name! :) Your issue was probably just that strings take a hot minute to stretch out when they're new.

I made a couple of these as well. At first, I was happy with them, but, the moment the novelty wore off, I decided it was a waste of filament. Here is why... 1. The friction tuners are not intended for plastic. I am a very gentle player, but I could not get the silly thing to stay in tune for more than a few seconds. I tried adding felt washers, which extended play time to maybe 45 seconds, but still too unstable for practical use. 2. I printed my neck as intended, but still had the same problem you did with your first neck. Also, trying to fix it with the truss rod broke the truss rod. So, I tried reprinting the truss rod with 100% infill and the neck with also much more infill. I redesigned the body to fit geared tuners. I even printed geared tuners out of ABS to try to experiment. (They broke under tension) Mark II worked better and I had a blast with it for a couple weeks until I noticed the neck continuously bowing. Eventually it was unplayable, and again, the truss rod broke trying to adjust this. Finally, I made one out of scrap softwood (from a bed slat my kid outgrew) using hand tools, and so far, that one has held up longer than either of the printed ones. Funny thing is that, considering the cost of filament and all of the futile redesigning in CAD, the wood one was both cheaper and quicker.

Fun video. I've been thinking about printing an ukulele. You might want to try it with a different set of strings. Might sound better and stay in tune. I've noticed some ukuleles sound better with Worth, some better with Aquilla, etc.

I’ll stick to my Risa uke solid, properly all solid wood with a hollow bit for the pickup, planetary geared tuners, zero fret for intonation, real frets.

Thanks for the vid, really interesting

Did you ever figure out the pickup problem?

better tuning can be obtained switching to geared tuning pegs

can you please show me how to insert the strings? I wasn’t able to see it well in the video. edit: I found it was easier to feed fishing line through, then tie the fishing line to the string and pull it through after wrapping the fishing line around a screwdriver.

Interesting project. Why not buy a fretboard with metal frets and glue it on? The sound is really dampened and muddy. It would be better with steel strings and humbucker pickup.

Hello! I am trying this project - what did you use to get the strings to go through? Even with new strings, I'm having some trouble with that step :/

What kind of pocket knife was that?

I want. How can I buy It?

Do you think the 3d design will work as a left handed uke?

I was wondering if you had to use the electronic part

So the printer, plans, etc..only costs 10$? Wow!

Its a cool ukulele, but its too quiet. I prefer the Ka Mua travel ukulele. It uses geared tuners instead.

There are fully plastic ukuleles that cost 10bucks sounding waaay better that this one. Still a cool project, but not worth it

Waste of time and money. Stick with the old black one. It may have been cheap, but I bet it plays ok.
