Parametric Slotted Jack Pad

My Fiat 500 Abarth features welded seam jack points, necessitating a simple adapter to lift the car without warping the seam. This adapter's SCAD file allows users to set the puck diameter and define its maximum dimensions. For instance, if one of your lift points is too close to another rail, it can clip the sides or ends. After measuring everything, I discovered that my printed part did not clip off any corners, but the code remains in place. Key benefits include: * A precise fit * Magnets that hold the adapter firmly in position while placing the jack * When the car is on the puck, it is mere millimeters away from the jack itself. In the event of a total failure of my printed part, the car will still be supported by my jack. * The car remains centered over the jack very effectively. Commercial pucks are significantly taller and appear less forgiving in the presence of lateral forces. * I have lifted the car several times without visible damage to its underside. Potential drawbacks include: * Cast pucks will not shear like 3D printed parts can. My greatest fear is applying enough sideways force on the puck that it shears off one side, causing the car to come off the jack. Working on a smooth garage floor rather than the street has alleviated those concerns. Updates have been made to address these issues: * The adapter now features rounded outer edges * Screws are located at the bottom to reduce the risk of shearing off one side * Embedded magnets (10mm in diameter and 10mm thick) enable users to stick the adapter in place before guiding the jack to it * The code has been cleaned up * A raft has been added for easier printing in nylon These updates have been thoroughly tested, and the PTCPE performed admirably. See my jack stand adapters on Thingiverse (https://www.thingiverse.com/thing:2948734) for a better illustration of the PCTPE's flexibility. The only issue is that the magnets need to be stronger.
