Tired of manually keeping your paperback open during a meal while occasionally spilling some tomato sauce over its pages?

This book openkeeper solves the problem:

• Print it. It is only 175 mm long, so it may be printed even on a 150 x 150 mm 3D-printer (diagonally). Otherwiese see below.
• Glue it to a suitably sized glass or acrylic or polycararbonate or polystyrene tile by means of a double-sided sticky tape. I prefer a glass tile due to its weight.
• Eat with both hands while reading.
• Stay tidy.
