DSO138 case

thingiverse

I really like this design, except for the +/- buttons and slide switch - they just don't quite fit my board perfectly. The case won't close properly with the DSO138 inside, and the corners don't match up either. There's not enough space left on the board to make it work. I had to modify the board by recessing a square area, lowering the connector hole, and also recessing the corner tabs further into the cover. Luckily, I was able to reuse the printed cover by cutting out the snap portion and gluing my modified version onto it. The back cover for the case is still compatible with the original design if you just want to fit your board in there. Since I had to make changes to the original design anyway, I decided to make some improvements from the STL files. If only I'd gone with the F3D files instead, but downloading those individually would have been too much hassle. So here's what I changed: I made the slide switch oval-shaped, created an oval hole for it, and enlarged the recess for the switch a bit. I also touched up the slide switch slots to make post-cleaning easier, closed off the trigger hole, left one layer thickness so light could still shine through, removed some wording from the switch side, added a cable storage stand, and made the slots for the stand on the case's sides. Note that since I've already built my own case, I don't plan to print another one. I haven't printed out these updated files yet, so use them at your own risk - if you need to adjust the storage slot to make it sit flat with the main unit, let me know about it. My version is probably just a clone of the original, which means my corners might be different from theirs. The other issue I'm having is that my DSO138 can't trigger time resolution at 50ms or higher. After looking around online, I couldn't find anyone with the same problem - except for one person who had trouble triggering below 50ms. My firmware version is 60 and it works fine for triggers under 20ms, but after updating to firmware version 66, my trigger works much better at time bases above 20ms.
