Eraser Holder with Scraper

The study aimed to design, construct, and evaluate an eraser holder with a scraper to minimise messiness and residue collected from the user. The holder cleaned the eraser when inserted and storage when not in use. It featured a unique scraping mechanism that minimised messiness and constant inhalation of the powdery substance from the eraser when writing and erasing the writings on the board. The performance of the device was tested using a combination of actual testing and a rating scale to establish a structured and objective assessment compared to general observations. Results found that the device’s overall mean of 1.33 suggests the system's effectiveness in achieving study objectives and considering users' health benefits. Further research is recommended to identify flaws and improve its effectiveness.
