MendelMax 2 MM2 JD Z Isolators

thingiverse

This upgrade significantly outperforms standard isolators, effectively counteracting any tilt caused by the Z nut. The contact patch is identical to or even smaller than that of the original isolator, but it does an excellent job of balancing the load on the nut while substantially reducing the impact of wobble triggered by screw movement. As a result, it minimizes it as much as the stock plates used in MM2 allow. Make sure to carefully clean up any flash from the slot before installation, and drill out the mounting holes to around 2.8mm or slightly more. The stock screws should be fine on their own, though using a washer between the nut and mounting screw can offer additional support. Turn off support material when printing this object. A total wall thickness of 1mm, with both top and bottom layers being equally thick, and an infill density of at least 20% are recommended settings for optimal results. During the assembly process, ensure that there aren't any higher points along the top ridge compared to the rest of it. If there are any such irregularities, a gentle touch of sandpaper should suffice in smoothing them out. Once complete, apply a thin film of silicone grease directly onto the metal X-axis plate's contact surface. This modification pairs well with my other design: the thrust bearing holder can be found on Thingiverse (http://www.thingiverse.com/thing:750603).
