QRS Player Piano Music Roll

thingiverse

This is a replacement "Music Roll" for QRS Player-Piano music rolls. On a player piano, this is required to hold the music roll centered, while allowing it to rotate freely. Originally, we lost several of these ends which are required to insert the music roll into a player piano and play them. Upon trying to use the ends on some music, I found that there isn't a standard size for all rolls- some use different-sized cardboard, thus I made the entire roll from scratch to get around this problem. If you have a cardboard roll the same size as most of mine, you could print just the end cap, or just the drive end. Note that the drive end must be glued. The cap end does not need glued.
