MMU Buffer

prusaprinters

<p>This is my version of the buffer required for the MMU (or MMU2s)</p> <p>I based my design on other similar buffers but wanted to add some modifications so I redesigned this one completely from scratch.</p> <p>The wheel turns very smoothly on a 6200 bearing.</p> <p>I wanted a relatively big wheel so the turn radius is not too tight to avoid friction. The total assembly is 12.5cm tall and 14cm wide.</p> <p>2 M10 fittings guide a 4mm PTFE tube all the way to the wheel.</p> <p>Friction is very low.</p> <p>Also a nice feature is the wheel turning while printing.</p> <p>Parts needed :</p> <ul> <li>4 printed parts</li> <li>2 x M10 PTFE fittings</li> <li>PTFE tube</li> <li>1 x M3x30 bolt</li> <li>1 x M3 nut</li> <li>2 x zipties</li> <li>1 x 6200 bearing (10x30x9)</li> </ul> <h3>Print instructions</h3><p>Printed with PETG Prusament Galaxy Black</p> <p>Layer height : 0.2mm<br/> 3 perimeters<br/> 5 top &amp; bottom layers<br/> 20% gyroid infill<br/> No supports required</p> <p>Print time : approximately 16 hours<br/> Plastic required : +- 150g</p>
