spark plug puller

On my BMW R1100RT motorcycle, the spark plugs are notoriously difficult to remove - there's hardly any room to grab hold of them.\r\n\r\nThe "spark plug puller" (or "spark plug extractor") is a game-changer.\r\n\r\n\r\n\r\nUpdate 16.6.2019: I managed to break two spark plugs trying to force out a particularly stubborn one.\r\nSo, I thickened the walls of the sparkplugex and reprinted it with 100% infill.\r\n\r\nWhile making those changes, I also enlarged the handle so my fingers can fit inside more comfortably.\r\n\r\n\r\nUpdate 26.6.2019: Check out this tube wrench extender that works perfectly in conjunction with the sparkplugex:\r\nhttps://www.thingiverse.com/thing:3715102
