Just for fun...
Guitarz only need a couple of rubber (or stretchy nylon) bands to complete a playable, tuneable mini guitar that's styled after an electric guitar. Just pick he rubber band strings or strum away....
There is an internal cavity that has been designed in.to improve the sound. As with a real guitar, tuning is all important. Once you have tuned your Guitarz, you can play a basic tune on them. Obviously they aren't loud as a full size metal stringed guitar but with a bit of tuning they can deliver a surprising range of notes and even be strummed.
This is an easy and fun print. The body of Guitarz is almost hollow however there is a small amount of designed in permanent support structure so no support is required (for PLA prints). Using support could result in the body being filled, not hollow, which will affect the sound output. The hollow body, albeit a small area, makes a difference.
Preparing your Guitarz to play post print is easy.... just run 1 / 2 / 4 rubber bands (depending on what you have available) around the band slots in your Guitarz making sure each band follows its respective slot (Refer to the images provided).
Tension can be adjusted by wrapping the rubber band/s around the pins on the underside which will alter the note when the band is picked. Altering the position of the rubber bands around each end of your Guitarz will also affect the tension and note created when picked or strummed. Tuning can be a bit fiddly and variable (as rubber bands will stretch etc.) but easy to do with a bit of experience.
Obviously this will never match a real guitar but, as a fun 3D printed musical instrument, once you've played around with the band tensions it's surprising how readily you can play a few simple notes to make a tune.... and you can even strum them.
At standard scale Guitarz are 160mm in length. Scaling up is no problem but scaling down may make fitment of rubber bands and tuning difficult (...the slots will reduce in size)
To make Guitarz multi-color pause your machine and change filament at approx. 76% and 96% progress (with a 1mm raft)
Have fun with your Guitarz!
