Simple buffing/polishing wheel

prusaprinters

<p>This project is just a simple two-part buffing/polishing wheel, onto which you just attach some kind of cloth or chamois with a rubber band. An M5 bolt is used as the shaft, just chuck it into your drill and start polishing.</p> <p>The top piece is meant to be used alone, if desired, and is 4 cm in diameter. The optional spreader is 8 cm in diameter.</p> <p>This project was inspired by one I saw on that other, slow model site. :-P</p> <h3>Print instructions</h3><ul> <li><p>Print the top piece in some durable plastic (Atomic Emerald Green translucent PETG shown here)</p> </li> <li><p>Print the spreader part in something flexible (Sain Smart Bright Green TPU shown here).</p> </li> </ul> <p>Press an M5 x 30-40 mm hex-head bolt into the bottom of the top piece, seating it into its recess, then thread a nut over the bolt and secure it.</p> <p>Press a couple of M3 x 11-14 mm screws into the bottom of the spreader, align the two pieces and press them together, then secure with nuts. Don't over-tighten them, this is TPU after all. :-)</p>
