grip assist

thingiverse

Ball end for wall scraper attachment. To get more grip when using the hand scraper, I discovered it's helpful to place my palm on the end of the shaft. However, this can become uncomfortable over time, particularly when the foam grips start moving around. To alleviate the pressure on my palm, I designed a ball-shaped attachment that fits onto the end of the shaft. The diameter of the shaft is approximately 19.5 millimeters, so I made the hole in the attachment slightly larger at 20 millimeters. The diameter of the ball itself is 80 millimeters. In retrospect, I think a smaller size of around 60 or 70 millimeters would have worked better for my medium-sized hands. Nevertheless, it performed well enough and I didn't need to do any extensive scraping, so I left it as is. A Sketchup 2017 file is included if you'd like to make any adjustments to the design.
