I recently bought the 50 meter roll of 30 note music box tape. The problem is that it slips half of the time. I saw posts of people with similar problems, and the user skyriver claims to have solved it... But I can't seem to be able acces the website. If anyone has solutions, or can at least retell what skyriver's solution was, I'd be grateful.
Basicly he 3d printed a part that adds tension to the top shaft thus resolving the issue.
Actually, I just finish reading the article and he cut a safety pin. Then attached it to both shafts thus making the 3d printed part unnecessary.
