Parametric D-Sub backshell housing

<p>Another D-Sub housing?</p> <p>Actually I was surprised to not find more and better models out there already...</p> <p>D-Sub connectors are quite commonly used and I usually have the connectors in my junk-boxes. But what about the housings? For the first they are often quite pricy in comparison to the connectors and they are also a bit bulky. So why not store a file instead and print them on demand?</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Wanhao</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Wanhao Duplicator i3 V2</p></div> <p><strong>Rafts:</strong></p> <p>Doesn't Matter</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>0.2 mm</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20%</p></div> <p><strong>Filament:</strong> Clas Ohlson PLA orange</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>The design can be printed without supports. There might be some stringing inside the hole for the hex nuts, but this can be easily cleaned out.</p></div> Post-Printing ============= <p>You need to print two copies of the shell. Use two M3 x 15mm screws to clamp the two halves together.</p> <h3>How I Designed This</h3> <p>The design is based on commonly available shell housing for D-Sub connectors. I went for a design with screws instead of snaps for stability and longevity reasons. The screw holes are countersunk M3x15 screws and hex nuts.rnrnThe dimensions of the D-Sub connectors are taken from the datasheets of ITT Cannon, Assmann and PDI with some averaging between the values. The design has been tested with 9-pin, 15-pin (dual row), and 25-pin connectors.rnrnAs for other shells this design consists of two identical halves.</p> </p></p></p> Category: Electronics
