DSO138 case

Last crawled date: 4 years, 2 months ago

I like this design(except the +/- buttons and the slide switch), however this is not a exact fit for my board. I can't close the case with the DSO138 inside, corners does not fit and not enough space left for the board. Had to make the board recess square, lowered the connector hole and also recess the corner tabs down further in the cover. Managed to reuse the printed cover by cutting out the snap portion and glue part of my version to it. Also the back cover for the case is compatible with the original design, if you just want to fit the board in.
Since I have to edit the original design, I might as well make it the way I like. So I made the following change from the STL files. Should have gone with the F3D files, but there're too many extra steps to download those files individually.
In summary, I made the slide switch oval, made the slide switch hole oval, recess for the slide switch a bit larger, touched up the slide switch slots to reduce the post clean up, close the trigger hole and left with one layer thickness(light can still shine through), remove some wordings from the switch side, created a cable storage stand and made the slots for the stand to the side of the case.
[NOTE] Since I already made my case, I do not plan to print another one. I have NOT printed the updated files, so try it at your own risk. If the storage slot needs to move up/down to sit flat with the main unit, let me know.
My version is most likely a clone one, so the corner might be different than the original.
The other problem I have is it can't trigger the time resolution at 50ms and above. I can't find the same issue online, except one complains can't trigger bellow 50ms and that is opposite of my issue. The firmware version on mine is 60 and triggers for 20ms or below work as expected. After updated the firmware to 66, I can see the trigger works much better and behaves as it should for the time base greater than 20ms.
