Case for NanoVNA (white gecko)

prusaprinters

<p>This is a case for a variation of the NanoVNA (Vector Network Analyzer, a radio tool), I got a white one with a gecko on the front, it comes with a front and rear PCB but I didn't felt it got enough protection from that, so I wanted to add some sides and protrusions to cover the switches and connectors.</p> <p>Note: There seems to be a new version of the white NanoVNA with USB-C, and it won't fit in this case.</p> <p>Features:<br/> Protects your VNA better.<br/> Storage bin too keep track of calibration references (and a few other adapters if you want.<br/> Storage bin cover can be used as stylus.<br/> Raised edges around power switch makes it harder to turn on accidentally.<br/> Makes the user input switch easier to maneuver.<br/> Looks and feels more like a finished product.<br/> More space for the battery.</p> <p>Note: you might need other/extra fasteners.</p> <h3> Print Settings</h3> <p><strong>Rafts:</strong></p> <p>Yes</p> <p><p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div></p> <p><strong>Notes:</strong></p> <p>The top part of the case need to be flipped upside down in the slicer.</p> <p>Raft is recommended.</p> <p>Supports are necessary.</p> <p>Use a filament that's somewhat see-thru if you want to see the LEDs.</p> <h3> Post-Printing</h3> <p><strong>Take it apart and prepare the VNA</strong></p> <p><div><p>Take apart your VNA by removing the screws.<br/> Remove the nylon distances and put them back with an extra M2.5 washer on the backside.</p> <p><strong>Clean up supports</strong></p> <p><div><p>In my experience cleaning up from the supports take a bit of work, I ended up scraping the contact surface in the back with a chisel to make the screws reach.</p> If you don't want or can't fix it you could just blue the case together instead.</div></p> <p><strong>Mount the VNA in the case</strong></p> <p>Put the VNA in the bottom half of the bumper, put the front bumper on.<br/> Put in the front PCB, screw it down.<br/> Flip the assembly over.<br/> Put the rear PCB in and screw it down.</p> <h3> How I Designed This</h3> <p>Designed with OnShape: <a href="https://cad.onshape.com/documents/f627fad51d186bd22ffd3c33/w/7de0872f391ecd8e806e38c5/e/31aae81f8991745c2cd5d3ef">https://cad.onshape.com/documents/f627fad51d186bd22ffd3c33/w/7de0872f391ecd8e806e38c5/e/31aae81f8991745c2cd5d3ef</a></p> </div></p></p> Category: Tool Holders & Boxes
