Stabilised Prusa Mini Z Bottom

prusaprinters

<p>A stabilised Z bottom to prevent side-to-side rocking.</p> <h3>Print instructions</h3><p>This is a remix of the Original Prusa Mini Z Bottom (R7) to prevent the printer rocking side-to-side and give better stabilisation.</p> <p>In the original part the rubber foot is positioned quite close to the right hand Y extrusion which allows the printer to rock side-to-side if the top of the Z extrusion is gently nudged.</p> <p>I have moved the foot much further out so that it is positioned directly under the Z extrusion. This completely eliminates the rocking.</p> <p>I have also added a longer bracket where the part attaches to the Y extrusion. This provides extra stability and rigidity to the Z assembly.</p> <p>The only extra hardware you will need is a drop-in T-nut and matching screw @ 20mm long.</p> <p>There are 3 STL files, each with a different sized fixing hole - M3, M4 &amp; m5. The 2 original fixing holes are still M3.</p> <p>To print on the Mini you will need to rotate the model by 58° and centre on the bed.</p> <p>The original print parameters recommended by Prusa should be used. Print in PETG using the 0.2mm quality preset with the infill at 20%.</p>
