Book opener / Thumb holder

thingiverse

Do you enjoy reading books? Frequently, these softcover books can be a challenge to read at an angle or overhead, such as when lying in bed. This little helper eliminates that problem. Simply place it on your thumb (the small tip upwards and the rounded edge between the sides) and enjoy reading. You can knot a wool string or ribbon to one of the sideholes to use it as a bookmark. There are two sizes available - 18mm and 22mm in diameter, suitable for most human thumbs. If you prefer a customized fit, feel free to scale it according to your thumb size; however, be cautious not to make it too small. Please measure your thumb thickness beforehand to avoid any potential issues. Have fun with it! And now, for my German-speaking audience: Do you like reading books and find it frustrating when they don't stay open? Especially with these softcover books. Here's a little tool that can help ease the process. Simply place it on the tip of your thumb (with the tip facing upwards) and hold the book in place. It's a significant relief while reading. You can also knot a wool thread or ribbon to one side to use as a bookmark. There are two sizes available - 18mm and 22mm inner diameter, suitable for most thumbs. You can customize them to fit your thumb by scaling; however, don't overdo it (I'm not responsible if you end up with a poorly fitting model). Maybe just measure your thumb thickness beforehand. Have fun printing!
