Adjustable roller and endstops, Jazala-J1 3D printer

The rollers on the X axis had become loose allowing the print head to rock and tip, making for progressively worse prints. This project allows the top rollers on the X axis to be kept snug. One other advantage of this is that the top rollers are twice as far apart giving a steadier mount. The X stop needed to be moved. The Z stop was replaced after the old part failed. Also see this item: https://www.thingiverse.com/thing:3895787 as it has the micrometer adjustment. for the z axis. The other half of the z stop. I printed all parts with .3 layer height. 20% infill. 3 wall thicknesses. As long as the head cooling fan is running, the roller mount stays near ambient.
