TinySA/NanoVNA-H Case

thingiverse

This thing is a case for the tinySA Spectrum Analyzer, along with some accessories. It should ALSO work for the NanoVNA-H product, which uses the identical form form factor. This case is designed to fit ONLY the tinySA (or NanoVNA-H) and perhaps a few small items between the connectors (loose). If you are interested in a larger case that can hold the accessories that came with the tinySA, please check this Thing (which this smaller one was based on): https://www.thingiverse.com/thing:4916912 This case is designed to allow for leaving SMA connector savers (installed on the inputs of the tinySA -- which I don't use, but was requested by other users). I can't guarantee that yours will fit, but if they look like these they should work: https://www.amazon.com/gp/product/B0814S5QPL?ie=UTF8&psc=1&linkCode=sl1&tag=spiffspace-20&linkId=a7acfefb0f53d2f21055a1c89cc16243&language=en_US&ref_=as_li_ss_tl There are three STL files provided here, one for the lower case, and two for the upper case. The variations between the upper case models is for a specific foam I used for my build. I used two pieces of 3.25mm foam for the top case, and a thin 1mm piece of rubber-like material in the bottom case. The "case_upper_foam" file is for this application. The "case_upper_nofoam" file substitues protrusions in the model that replace the foam pieces. The build for this "nofoam" assembly that omits the two foam pads in the top AND the 1mm thick rubber piece in the bottom case, and leaves 1mm more clearance. The fit for this one will be a bit more sloppy vertically, but should work fine. I have NOT built or printed this option, but I am confident it will work fine. You can probably source some thin material to take up any slop in the assembly - even the sheet of foam that is provided in the original tinySA packaging box could work (if you can extract it without it tearing). I can't promise that the following will work, but these two items could work if you want to get foam that can work for the "foam" version: Upper Foam: https://www.amazon.com/Sheets-Adhesive-Neoprene-Insulation-Vibration/dp/B08P1XQMQH?dchild=1&keywords=Closed%2BCell%2BFoam%2BSheet&qid=1627667613&sr=8-5&th=1&linkCode=sl1&tag=spiffspace-20&linkId=0ed46c65fcf61a045c64c531f23ea076&language=en_US&ref_=as_li_ss_tl The above should be a 5-pack of 12" x 8" x 1/8" thick neoprene rubber closed cell foam - MAKE SURE it is the 1/8" thick option! Lower Pad: https://www.amazon.com/Sheets-Adhesive-Neoprene-Insulation-Vibration/dp/B08P1XQMQH?dchild=1&keywords=Closed%2BCell%2BFoam%2BSheet&qid=1627667613&sr=8-5&th=1&linkCode=sl1&tag=spiffspace-20&linkId=0ed46c65fcf61a045c64c531f23ea076&language=en_US&ref_=as_li_ss_tl The above is a pack of 10 pieces of roughly 8" x 10" 1mm sheets. Both of the above links are for WAY more material than you would need, but it is all I was able to find online that might be equivalent to the materials I had on hand. Hardware required: (2) M3 x 30mm long socket head cap screws (2) M3 nylon locknuts (4) M3 flat washers (approx 0.5mm thick) NOTE: I don't have any printed photos of this, as I haven't printed it (I only printed the larger version that I linked to previously), but I shared this with some mailing list members and they confirmed it worked and printed fine.
