Diving Board Corner Sphere (protect pool solar cover from snags)

thingiverse

The way my pool is situated, the only way to wind up the solar cover is to drag it over the diving board. This usually works well, but after a season or two the cover tends to snag on the diving board corners. This thing solves the problem. It is simply a sphere several inches in diameter with a corner notched out. I put the spheres on the corners of the diving board as shown in the photo, and there is no longer a corner to snag the solar cover. You may of course have to adjust the size of the notched out corner to fit your own diving board. Measure it first and then add a few millimeters slack. My diving board was 31mm thick (about 1.25 inches) so I used 34 mm as the cube height used to cut the notch. If your board happens to be 1.25 inches then you win! Otherwise just adjust it in the openscad and have fun in the sun with no snags! NOTE: if your cover is attached to the reel (mine is not) then make sure you put the corners on before you unreel the cover. The spheres should be snug enough that they won't come off as you deploy the cover, then they'll be in place when it's time to wind the cover back up. Instructions: Measure the thickness of your diving board near the corners. If it happens to be near 1.25 inches (31 or so mm) then you can use the stl. Otherwise, edit the openscad file and adjust the height of the cube used to cut the notch from 34 mm to whatever your board is plus a few mm extra. Print 2 of them. When you need to roll up your cover, put them on the board first. No more snags! If you print these out of PLA you might want to spray them with waterproof sealer so they don't degrade. Remove them before people use the pool for swimming, of course.
