Assistive Magnetic Tile Toy Grips

thingiverse

This is a set of grip ideas designed to help children with disabilities interact with a game that uses tiles on a board to program a small robot. The tiles are coincidentally magnetic, and these grips should allow more children to engage with the game than before. Originally created for a user request through my employer's (the Neil Squire Society) Makers Making Change initiative. This has undergone some user testing with clients, and it is posted here in the hope that someone else might find a use for lightly magnetic pickup grips. Designs should be relatively easy to modify in OpenSCAD: the overall dimensions and magnet sizes are listed at the top of the code. As provided, these designs use the following parts: * 0.25" x 0.1" Rare-Earth magnet, Lee Valley item 99K3101 * 3/8" Cup for 1/4" Magnet, Lee Valley item 99K3251 * 3/8" High-Friction Disc for 1/4" Magnet, Lee Valley item 99K3450 The magnet cup greatly increases the pull of the magnet, and the high friction disc should prevent the tile from sliding about. Each magnet has a tiny red dot on one face: the dot should be hidden inside the cup for it to attract a game tile. Note that you only get one shot fitting a magnet in the cup: once it's in, it's never coming out. This is the fourth revision of the grips: they now use a smaller magnet in a cup, covered with a non-slip sticker. See companion design [Draft] Game Go Button.
