CTC Bizer Dual (and others) doors and lid

prusaprinters

<p>This project started with the hinges I found on this platform. From there it progressed in completely closing my CTC with doors and a lid/top-cover. I planned on adding hinges to the lid as well, but decided to keep it separated from the printer so I didn't need to drill more holes close to the y-axis rod and because the lid, when opened, would need to go further to the back than the position of my printer allows. Now I just take it off and put it aside, when necessary.</p> <p>I didn't change the hinges, but did redraw them in Freecad. New stl files are attached.</p> <p>The DXF files are the cutting template for the doors and top-cover plates. The front doors are a bit larger than the front opening, the side doors fit into the side openings. I used 3 mm acrylic which I cut by hand using a special knife. Laser cutting is preferred....</p> <p>Because of the thickness of the acrylic, I added spacers between the hinges and the doors. 6 mm for the side doors and, in the beginning, 3 mm for the front doors. I later changed them for 2mm spacers for a less tight fit.</p> <p>I made drill templates for the printer case and for the doors. They can be mirrored by physically turning them around, so you need just one for each door/side.</p> <p>On the top-cover I used the corner parts as a drill template (Tape it together first to be sure all plates are positioned right)</p> <p>I screwed everything together using M3 nuts and M3 allen bolts (M3x8, M3x10, M3x12 &amp; M3x16). The knobs allow use of round magnets (12 x 2 mm). You can then put some flat (iron) screw is the case that allow the magnets to snap to the case.</p> <p>For the top-cover/lid I used brushes from the local hardware store. These brushes are used in (Deltafix) mailbox weather strips. They're easily cut to size and slide in the brackets. This design is a result of the filament holders I decided to use. It allows the filament, and the extruder cables, to go through and still keep the entire setup closed.</p> <p>All the parts:</p> <p>Doors:</p> <p>8x Hinge, Hingebracket &amp; Pin; 2 for each door</p> <p>4x 2mm spacers; 2 for each front door (3mm spacer for tight fit)</p> <p>4x 6mm spacers; 2 for each side door</p> <p>12x M3x12; Front door hinge</p> <p>12x M3x16; Side door hinge</p> <p>2x Front door knob</p> <p>4x M3x8</p> <p>2x Side door knob</p> <p>4x M3x10</p> <p>32x M3 nut</p> <p>Top-cover/lid:</p> <p>Acrylic plates:</p> <p>Top plate 400 x 270 x 3 mm</p> <p>Front plate 400 x 150 x 3 mm</p> <p>(2) Side plates 264 x 150 x 3 mm</p> <p>(2) Back plates 170 x 150 x 3 mm</p> <p>4x Corner inside &amp; Corner outside; for all 4 top corners</p> <p>1x Rear bridge inside &amp; outside; joins 2 rear acrylic plates</p> <p>2x LF (Left Front) + RR (Right Rear) inside &amp; outside corners; bottom corners</p> <p>2x LR (Left Rear) + RF (Right Front) inside &amp; outside corners; bottom corners</p> <p>70x M3x12</p> <p>70x M3 nut</p> <p>Optional:</p> <p>2x L+R Brush holders; Left &amp; Right brush holder</p> <p>1x Rear brush holder: &lt;--</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>CTC Bizer Dual</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.2 mm</p></div> <p><strong>Infill:</strong></p> <p>100%</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>I used 100% infill, but this might be overkill.<br/> I only used supports on the front door knob because the magnets hang over the 3mm acrylic doors. <h3>Post-Printing</h3> <p>Some of the hinges and hingebrackets needed some work to make them fit smoothly.</p> </p></div></p></p> Category: 3D Printer Parts
