Domestic manhole cover key

thingiverse

There is nothing exciting about this - it is just a manhole cover key (the sort that fits into a slot and rotates to allow a lifting force to be applied). I would advise printing it so that the filaments line-up with the direction of force - and may be use acetone to weld the filaments if you are using ABS. Anyway a useful tool to speed the investigation of 'unpleasantness'. I have tested it and it lifts my manhole covers with ease. Have fun!
