Music book page holder

Simple gadget to keep books/music open. I use it when playing the piano to keep my music in place when practicing.

Printing tips:

• Use PETG if your PLA doesn't keep it's shape well enough 
• Concentric bottom layer looks quite nice!

Remix based on @dromanol's design - I removed the loop at the top and ended up redesigning it from scratch to get it to flow smoothly (and the general shape is almost identical).
