Shouldn’t this forum go under the build event section
This is under the lab event section because along with the build portion, there is a test section as well.
Why can't it be under both?
This way, all of the information about the event is gatheted together. If this thread gets really active, the mods might make a subforum for the build like they did with thermo.

Also, the rules say that the best value during the five seconds will be counted for the pitch score. Does this mean that if you had, say a Slide whistle, and slid from a flat F to a sharp F during those 5 seconds—because you hit an in tune F at some point, you would get max points?
that is a clever idea but only deices with a quick decay time can have multiple attacks on the note. ( hitting a mallet or plucking string) and a slide whistle doesnt meet those constraints
But if you kept blowing for 5 seconds straight, wouldn't it still count as a single attack?

That plan relies on the tuner refreshing continuously. If the tuner display refreshes infrequently, even though the slide whistle passes through F, the tuner may not capture that very moment. The judge may also be blinking at that very moment. In general, even though you’re guaranteed to be in tune at some point during the 5 seconds if you use your strategy, it’s not a safe strategy because there’s no guarantee the judge/tuner will catch the very moment you’re in tune.

The scoring is based off of the closest cent to the target. I would hope that tuners would record continuously on some sort of device (like labquest does in physics labs) because if the judge is simply observing the device for the best measurement he/she might miss what would be the closest cent. As a musician, I know that tuners change their measurement very quickly and it would be very inaccurate to simply observe the tuner as a way to record the score. I have no idea how the cent value is going to be recorded in competition, but if it is done by eye I would agree that it would be risky to use the method Squad thought of.

Edit: Found a site that might give an example of what I'm talking about here. The software records statistics on both the volume and the pitch.

I think everyone is missing a very important part of that rule, which is the first few words that say you can only play 1 pitch....

At what point would it not be considered one pitch? Just as an example, if you were on let’s say a string instrument like a violin, you can place your finger down on an ‘A’ and then rotate it very slightly so that it covers what is most definitely the exact cent of 440 (assuming it’s A4). It wouldn’t sound as a different pitch at all, just very fine adjustments in the intonation that would be barely noticeable to the ear but would basically be guaranteed full points. I’m not sure if I made any sense just now but it’s hard for me to describe.

If you're sliding on a slide whistle, it's obviously not one pitch. But I think the main takeaway is that you shouldn't press your luck as to flexibility of the rules.

For creating a 3D printed stringed instrument what is considered a modification? Would it be considered original I used a 3D scanner to scan an instrument to be a base starting file to render off of? Or, would it still be considered original to use files off of sources like Thingiverse and modify those. And, what would be considered a modification?

Not official etc etc, but if youre gonna 3D print an instrument, I think youre covered on the modification and have much bigger things to worry about. I would seriously consider the amount of tension you will be placing on the printed parts and think about (or calculate) deformation. I would be very worried about keeping a 3D printed string instrument in tune

The general preference is to have only one thread for each event for the hybrid lab events that have both test and device portions. If there is significant forum support to put these hybrid events into the Build forums, or to create a new "Hybrid Events" subforum, then that is something we can consider, but right now the policy using Lab Events has worked.
