Old school cheating device

This compact 3D-printed tool is your perfect companion for recalling formulas and concepts during challenging moments. Small enough to fit in your pocket or pencil case, it’s ideal for school or on-the-go use. For the best results, we recommend printing it with a layer height of 0.08 or 0.1 mm.

Remember to place a staple at the beginning and end of the paper strip for a secure hold.
