Top screw only leveling for Tevo Tornado

thingiverse

I know most people like to use larger thumb screws for leveling their machines, but if you haven't put in- or don't want to put in- o-rings between the bed screws and glass bed on your Tevo Tornado, this is an alternative. It's simply a press fit retainer for the stock thumb screw that prevents it from turning as you level your printer with an allen key.
