Description	A field box for the NanoVNA-H4, includes lots of room for jumper storage, BNC adapters, all calibration standards, etc.

Notes

• Printed in PETG for case, latches, and inner tray.
• Requires a total of 6 x M3 screws, 30 mm long - two for each of the two latches at the front and two for the rear hinges
• Did not print the TPU grommet, and it works fine, but just won’t be as damp proof.
• Latches printed on their sides.
• Inner tray a very snug fit, so make sure you get the orientation and side correct.
• Fit for the NanoVNA itself could do with being a bit tighter in my opinion. Even with the stick out controls for the power and the rocker dial. there’s still another 1-2 mm gap at the top/bottom and side.
• The holes for the calibration adapters are rather fiddly. I’m not sure how it could be improved as the calibration adapters themselves are fiddly. I think having them stored flat rather than on an edge would be better, but I would have to try it.
• I added a stickers to mine rather than printing info directly to it as I included my callsign which will change as I qualify for higher levels of proficiency.
• A little extra/deeper storage would have been nice as I added a couple of SMA to SO239 connector cables, and the folded instructions sheet that came with the NanoVNA-H4.
  • The designers photo shows they have added SMA to BNC single piece adapters rather than the 15 cm style adapter cables I have, so that single element option would probably help with this.
• Overall, a nice rugged case. I feel my NanoVNA-H4 is well protected, but at the price of something that is, necessarily, a little bulky and a little heavy for what it is. I think if I were to redo this I would consider stronger material with less infill, and a few tweaks to the inlay tray to suit my own needs better.
