Stiffer X-End for Prusa Mini with square nuts

prusaprinters

<p>The X-End is the part I find myself adjusting all the time for a level bed. This mod adds more stiffness and gives a proper thread for all screws. You can also easily pull out the pulley to the front, in contrast to the original prusa part.</p><p>Pros:</p><ul><li>Stiffer in all directions, less twisting</li><li>better long term stability (should hold alignment better)</li><li>can take out the Pulley easily (if you want to change something on the x carriage you don't have to remove the X-End)</li><li>less wear as all screws have metal to thread into</li></ul><p><strong>You need:</strong></p><ul><li>6 x M3 Squarenuts (2 should be in the old part)</li><li>4 x M3 8 mm cylinderhead screws</li><li>The other things from the original part</li></ul><p>As always: don't overtorque or you will break the part, even though this is fairly stable in PETG.</p><p><strong>Important for assembly:</strong> The part where the cylinder head screws sit protrudes a little bit to accomodate 8 mm screws. This part has to face the back side where the part cooling fan is or the X-Carriage can crash into the part (see photos). If you really want the screws on the other side, you could modify the part and use shorter screws.</p><p>&nbsp;</p>
