Last crawled date: 4 years, 4 months ago

An example of 3D model generated with my Gugulele OpenSCAD script… (see https://github.com/bguan/gugulele).
Decorative headless unibody gourd shaped design
Single rectangular through-body spine
Single oval off center sound hole
T-Bracing
Tail-end placement of Planetary tuners
3 pieces using M1.6 socket head screws or M2 self tapping wood screws
You can hear me playing the fully assembled unit in this demo youtube video: https://youtu.be/wjND_2x5BcE
Third Party Parts:
Spine/rods e.g. http://www.acpsales.com/.125-x-.325-Rectangular-Rod.html or https://dragonplate.com/ecart/product.asp?pID=749&cID=20
get a 24" long and cut it down to size, can't remember exactly...
if you don't use a rod, the neck will bow under string tension

Gotoh UPT-UBB-B Tuners e.g. http://www.theukulelesite.com/gotoh-upt-tuner-upgrade.html
its possible to use cheaper friction tuners, but need to play with shims and washers like this user http://www.thingiverse.com/make:325819
he uses https://www.amazon.com/gp/product/B002HFQ88Y

Screws (M1.6x12) for fretboard long holes e.g. http://www.amazon.com/dp/B00XP4OD5Q
can't remember how many you need, just buy a bag of 100

Screws (M1.6x4) for bridge and fretboard short (mid-line) holes e.g. https://www.amazon.com/dp/B00XP4ZWY2
can't remember how many you need, just buy a bag of 100

Lately I've been using M2 wood screws like these https://www.amazon.com/gp/product/B01MTKUV85
I printed this on big delta style printers, the model is oriented pointing up, like a flower vase. I use 100 micron, 33% lattice infill.
