Ukulele wall hanger

Wall mounted ukulele hanger. This will fit most ukulele with a 1.5" wide nut, which is the average width across brands. The throat is also wide enough for guitarlele type instruments with a nut width closer to 2". It's probably strong enough to support classical and steel string guitars as well, but use at your own risk. I designed this with the weight of an ukulele in mind and it's plenty strong for that.

Printing tips for body

I like PETG. PLA may work as well, but use at your own risk. I recommend 3 perimeters and 80% infill.

Printing tips for sleeves

Print with the softest TPU that you can. I use standard Ninjaflex, which is 85A. It's has just enough stiffness to print on a standard machine, but it's also just soft enough to squish a little when the instrument is hung. If you can manage something softer on your machine, even better. Assuming that you're not making tons of these, I also recommend using sequential printing for the sleeves. They come out a lot cleaner, but you'll be limited to a smaller amount of objects on the print bed.

If you have a multiple extruder setup, the first stl has all the parts arranged for printing as-is. Otherwise, I separated the body and sleeves into two files. 

Warning

I strongly suggest that you don't try printing everything in one go by using virtual mmu or virtual multiple extruders. Flex and hard filaments do not play nicely during filament changes. I do a lot of color and material changes regularly and I always flush extra filament during swaps. You WILL get a clog and it WILL cost you a lot more time if you try to shortcut the printing without actual multiple heads. Neither of the parts take very long to print, so save yourself some time and headache by printing them separately if you do not have the proper setup.

Happy printing!
