Celtic Guitar Cavity Decoration

This is a test upload, I made a quick acoustic guitar cavity decoration to see how the site works, It should just pop right into a 100mm acoustic guitar cavity.
Resize it based on your guitar's cavity, keep in mind that this is 99mm to 100mm inner diameter of the guitar aperture, at the 109.98mm outer ring full diameter.
So resize it accordingly to your guitar.
And obviously you will want to paint it after.
You can just pop this in or out whenever you want to use it, no glue or anything permanent.
I will make a bunch of these for everyone if people want it.
I will also make full sets, matching bridges and bridge pegs, as well as tuning thumb knobs and so on.
This was just a test, I will design my own instead of adapting a found item like this, again this was just a test.
Thank you for checking it out.

NOTE: You may have to sand down one side if your guitar neck is too close to the aperture, this happened to me, so I had to decide what side to make flat, and I kind of didn't sand it on the disc sander straight so I had to walk around the hole with it, making it more like a rounded spot than a flat spot.
Go me.
Anyway you may have to do that, so once you decide weather you like it squared or 45o, make sure you are happy with that decision before you sand down a 14hr print lol.
ALSO mine is a tad too small for the inner diameter of the hole, but nothing once around with either tape or thin felt won't fix.
I will design a better one, again this was only a test model to see how the site worked and if I wanted to use it or not.

NEW NOTE:
I have now included a model with the neck cut-out so you don't have to sand the damn thing if your neck extends down to the lip of the sound hole like mine does.
It fits way better too. (That 1mm difference is huge, no need to tape it at 100mm opening.)

It is tapered to wedge itself in like a cork, so you don't have to glue it, and you can change it out when ever you want.
Hopefully it will not buzz, I have it printing now, so I will find out when it is done if any anchors are needed between the over-lapping parts.
I will upload photos of the final product as soon as it finishes printing.
I used an item downloaded from Thingiverse and adapted it to a set ring for the guitar.
The original file I used for this quick test is:

Inside (Small OD, not actual ID) ring diameter to fit 100mm guitar cavity (99mm start tapered up to 101mm to press into orifice and fit snug like a tapered cork.)
Outer diameter is 109.98mm and overlaps roughly 5mm on either side of the guitar cavity.
