3D Printed Speaker V1

This is V1 of the 3D printed speaker. I've been trying to do this for quite some time now and I think I got it right – or at least I am on the right path. The speaker is fully 3D printed with only the amplifier board, magnets, and coil wire purchased from amazon. I will link them below. I am still experimenting with the amount of winds I should be making with the coil and the wire gauge so your comments about that below are greatly appreciated!

***Amount of winds***: 4 layers up and down the cone shaft. Start from the top and work your way down, then back up again.
