<p>Great for polishing 3d print with brass/copper/bronze and other metal-filled filaments (and rocks of course !)</p> <p>Remix from : <a href="https://www.thingiverse.com/thing:2744886">https://www.thingiverse.com/thing:2744886</a></p> <p>Almost fully redraw with the aim to make the structure with a CNC router and use part I already have (NEMA motor, 8 and 10mm rods, HDPE, electronic parts...).</p> <p>Notes :</p> <ul> <li>I have use 8mm rodes for rotating axis and 10mm for structure</li> <li>You can print the structure if you want, but the original one will use less material:</li> <li>use .stl for printing and .dxf for importing in your CNC software</li> <li>the frame is made of 15mm thick HDPE but wood or metal can be used if your CNC router is able to handle it.</li> <li>the electronic box will only fit the parts I use in the way I soldered them. You use something else to drive the motor, just don't print it.<br/> More details, BOM, photos, code and other sources on my git repository:<br/> <a href="https://framagit.org/arofarn/polisseur">https://framagit.org/arofarn/polisseur</a></li> </ul> <p>You can find vibration dampenning feet here:<br/> <a href="https://www.prusaprinters.org/prints/53965-vibration-dampenning-feet-for-rock-tumbler-w-squas">https://www.prusaprinters.org/prints/53965-vibration-dampenning-feet-for-rock-tumbler-w-squas</a></p> <p>EDIT : Add FreeCAD source file<br/> EDIT2 : Add gear protection cover (to keep finger safe)</p>
