easy and efficient bed tightener for Tronxy X1

This 2-part design fixes most of the trouble/wobble with the existing bed of Tronxy X1 printers.

It helps tighten the wheels around the aluminum profile, but it also keeps the wheels perpendiculat to the bed, once the bolt is tightened, which in turn reduces the wear on them.
Some people my have to file the 3rd wheel hole a bit in order to tighten the bed enough, as some early versions of the printer has them in the wrong place (!)

Just loosen the 3rd wheel slightly, tighten the M3 screw
