Here is a short animation showing the forward brust closeout in operation: https://youtu.be/rUzQMUAmMOg <h3>Discussion</h3> <p>This Dust Shoe supports the Dremel 4000 Router when mounted in a V1 Engineering MPCNC Primo CNC. The required mounts files are provided with the other .stl files attached. </p> <p>The Dust Shoe connects to a ShopVac or equivalent vacuum source having a 30mm solid hose extension. A flexible hose connects the extension tube to the vacuum source. The extension tube should be between 300 and 360mm in length. The flexible hose should be suspended overhead, centered on the work area and should have at least a 4 foot rise with ample slack so as not to place side loads on the tool anywhere within the work area.</p> <p>File <b>Dust-Shoe-Mount.stl</b> may be printed or cut (preferred) from 5mm Acrylic stock using the MPCNC router. Clear Acrylic sheet provides visability of the bit and milling area.</p> <p>The Dust Shoe is designed to have the aft portion fixed to the <b>Dust-Shoe-Mount</b> with is in turn attached to the <b>D4000-Lower-Mount</b>. The forward portion of the dust shoe is designed to slid onto the <b>Dust-Shoe-Mount</b> and to be held in place by four 5x10mm magnets, two on the fixed (aft) portion and two on the sliding (forward) portion. When installing the magnets make use the two haves of the Dust Shoe are attracting rather than repelling magnets.</p> <p>The brush stock listed below is 70mm in length. This is too long for most bit lengths and must be trimmed to approximately 55mm. Once trimmed the brush stock is cut to size and inserted between the <b>Fixed-Brush-Mount</b> and the <b>Fixed-Brush-Clamp</b> using 3 M3 screws and locknuts. In like manner cut another section of Brush stock and mount it between the <b>Sliding-Brush-Mount</b> and the <b>Sliding-Brush-Clamp</b> using 3 M3 screws and locknuts.</p> The <b>Sliding-Brush assembly</b> should now slide freely over the <b> Dust-Shoe-Mount</b> and be held in place by the four magnets. <H3>BOM</H3> <table border="1" cellpadding="8" > <tr> <th>Qty</th> <th>Item</th> <th>Source</th> </tr> <tr> <td>4</td> <td>M3x.5x20 Screws</td> <td><a href="https://www.amazon.com/Assortment-Lengths-Stainless-Machine-Hardware/dp/B0881X3Y4X"> https://www.amazon.com/Assortment-Lengths-Stainless-Machine-Hardware/dp/B0881X3Y4X</a></td> </tr> <tr> <td>2</td> <td>M3x.5x16 Screws</td> <td>Amazon</td> </tr> <tr> <td>3</td> <td>M3x.5x12 Screws</td> <td>See Above</td> </tr> <tr> <td>3</td> <td>M4x.7x16 Screws</td> <td>See Above</td> </tr> <tr> <td>2</td> <td>M5x.8x30 Screws</td> <td><a href="https://www.amazon.com/dp/B077WL4SBQ"> https://www.amazon.com/dp/B077WL4SBQ</a></td> </tr> <tr> <td>3</td> <td>M3 Square Nuts</td> <td><a href="https://www.amazon.com/gp/product/B018JPZNS6"> https://www.amazon.com/gp/product/B018JPZNS6</a></td> </tr> <tr> <td>7</td> <td>M3 Locknuts</td> <td><a href="https://www.amazon.com/Stainless-Steel-Assortment-Insert-Locknut/dp/B074PJV3N1"> https://www.amazon.com/Stainless-Steel-Assortment-Insert-Locknut/dp/B074PJV3N1</a></td> </tr> </tr> <tr> <td>3</td> <td>M4 Locknuts</td> <td>See Above</td> </tr> </tr> <tr> <td>2</td> <td>M5 Locknuts</td> <td>See Above</td> </tr> </tr> <tr> <td>4</td> <td>5x10mm Magnets</td> <td><a href="https://www.amazon.com/Round-Multi-Use-Magnets-Refrigerator-Project/dp/B07G83YWG3"> https://www.amazon.com/Round-Multi-Use-Magnets-Refrigerator-Project/dp/B07G83YWG3</a></td> </tr> </tr> <tr> <td>1</td> <td>Brush Stock</td> <td><a href="https://www.amazon.com/gp/product/B07VM6FG45"> https://www.amazon.com/gp/product/B07VM6FG45</a></td> </tr> </table>
