Ukelele Hook

The shape of this hook is tuned to closely fit a Kala Soprano Ukelele, with just a little bit of wiggle. It may fit other ukeleles well too, but there is quite a bit of variation in uke neck sizes, so check the following measurements before printing to roughly check whether it will fit.

• Fretboard at the topmost fret wire should be no wider than 36mm. • Headstock width (left–right) at 10mm above the fretboard should be about 40mm, and flare out (about a 20-30° angle) toward the top. • Headstock thickness (front–back) just below the tuning pegs should be 10-12mm, and increase slightly as it meets the fretboard. • Headstock should lean back from the neck a little, about a 15° angle.

Ukes that meet this description should fit very well. If you’re not sure, don't be afraid to just try and see. We should always avoid waste, but it’s not a huge investment of filament to run a test on this small part.

If your uke is about the right shape, but too big or small, you can try scaling the model slightly (95%–105%) in one or more dimensions. You might need to print several times to get a perfect fit, so keep detailed notes to avoid wasting filament unnecessarily.

For more control and flexibility than scaling, I highly recommend you tweak the original cad model in your browser, with the OnShape model. A free account may be required to make changes and download a custom STL.

For FDM printers, this model is best printed top-side down so there are no tricky overhangs.
