Classical Guitar Finger Picks

I recommend trying the latest version of this model, which is more comfortable and fits more securely - https://www.thingiverse.com/thing:6328011 This solution is intended for guitarists who do not have good nails, but would like to improve sound production. Most likely, you will have to print the model several times, adjusting the scale so that the product fits snugly on your finger. I used an elastic TPU and am very happy with the result.
