<p>Case for the CB2 Micro kit computer <a href="http://cb2.qrp.gr/">http://cb2.qrp.gr/</a> which is a cheap easy to build microcomputer which comes with games and a built in Basic editor, all running on an ATmega644.</p> <p>New version with logo changed to match the silkscreen and two 5.8mm hole to mount RCA connector for audio and composite video. Also exposed the jumpers by the DB9 connector.</p> <p>Case PCB to sidewall gap reduced to 1mm from 2mm for a snugger fit, and the clip pins tweaked for better fit too.</p> <p>Added version 2 of the 1.6mm shell with snap fit clips, the PCB pins now just hold it in place.</p> <p>Works well with Cura's dynamic quality at 0.2mm alsoin in PETG for durability.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>CR-10</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>~25%</p></div> <p><strong>Filament:</strong> <a href="https://www.amazon.com?linkCode=ll2&amp;tag=thingiverse09-20&amp;linkId=e4759bff1fa9a55a0f897d801ce2d765&amp;language=en_US&amp;ref_=as_li_ss_tl">Amazon</a> PLA <br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>My son made it but it needed a case so it doesn't short out anything when placed on conductive items :-) I search but there wasn't one so thought I would make one.<br/> No board/eagle file published so made it from manual measurements. <p>The top has cutouts for the expansion pins if you wish to use them.</p> <p>The PCB should sit on the mounting pins on the bottom and the top push down over and hold in place.</p> <p>First 3D object I've designed in a very long time and first for 3D printing and first time using Fusion 360 so a little rough and probably easily improved.</p> <p>I have made a few improvements since my last print for better alignment but it should be good to print.</p> <p>One thing is to check the finish on the pins and the locating holes they may need a clean up depending on how good your print is.</p> <p>Fusion 360 f3d file, OBJ and STL files included to edit as you see fit.</p> <p>Print the two half with flat face down, 0.2 no supports needed the walls are only 1mm which is two lines on my printer, strong enough for a fall down some stairs ;-)</p> </p></div></p></p></p> Category: Computer
