3½" and 5¼" drive bay covers

prusaprinters

<p>I forked Redertech's drive bay cover (<a href="https://www.thingiverse.com/thing:1188607">https://www.thingiverse.com/thing:1188607</a>), and created a version with vent holes, a version with vent holes and a single large hole near one end (for a large LED or similar), a 5¼" cover with holes, and a 5¼", 4-high cover with holes.</p> <p>Made them for one of my machines that has since lost all of its covers. The 5¼", 4-high one works well because the machine in question will never get any externally-accessible drives, so no worries about having to resize it some day or whatever.</p> <p>I didn't actually end up using the single 5¼" cover, so it's technically untested, but the 4-in-one is simply that one with one wall moved out 3x further, two more side clips, and more vent holes added, so it should be fine.</p> <h3>Print instructions</h3><h3>Licence: Creative Commons - Attribution Print Settings</h3> <p><strong>Printer Brand:</strong> RepRap</p> <p><strong>Printer:</strong> Prusa i3</p> <p><strong>Rafts:</strong> No</p> <p><strong>Supports:</strong> No</p> <p><strong>Resolution:</strong> 0.2 mm</p> <p><strong>Infill:</strong> 25%</p> <p><strong>Notes:</strong></p> <p>Important: You need good bed adhesion and you will have to slow your first layer down considerably to get these to print properly - lots and lots AND LOTS of small circles have to be drawn on that first layer. I set my first layer speed to 10 mm/sec (normally 40). If you are using Slic3r, you will probably have to set ALL of your extrusion widths to manual values when printing the 4-up one, as its design may confuse Slic3r (I used 0.5 mm across the board, with 0.075mm infill/perimeter overlap).</p> <h3> Post-Printing</h3> <p>I printed these with bright white Atomic PLA and, since I didn't have black on hand, let fly with a can of black gloss Krylon.</p> <h3> How I Designed This</h3> <p>Loaded the original file into Blender, bit of scaling to create the 5¼" version, and a lot of copy and paste to create a bunch of cylinders to act as a "die" to cut holes into the covers with, via Blender's boolean modifier.</p>
