Musical Cups

I made this boom-whacker style instrument. You can use any online videos/sheet music for boomwhackers to play these! To play it, take a pencil and hit the rim of the cup. Hitting the side will result in an off-pitch and dull sound. Printing Material: PLA had the best sound for me. Do not use PLA silk, it was lower for me. I didn't have multiple colors, so I had to print in one color. In addition, I know it uses a lot of filament, but it is worth it! Also, it's cheaper than many boomwhacker sets.Warning: B and A are a little flat.
