Console UART Sliding Case

Post by hominoid »

After doing the tango with the my console uart for years, always worried about it shorting on something, I found time to hammer out a simple two piece sliding case. I have wanted to make one for awhile but it was such a low priority that it wasn’t even on my projects list. In the end, it was an interesting opportunity to explore what worked for fastener-less micro cases, that could be printed with no support, using fused filament fabrication.

      ABS was used with the included stl which has 1.5mm thick walls. The material used might make a difference for such thin walls so the case can also be printed at different wall thicknesses like 1.75mm or 2mm. The top’s fit can also be adjusted using the tolerance variable as noted at the beginning of the source file. The case is basically parametric so it may be useful for other small PCB and micro-controllers with some minor modification.

        Great! Too bad HK is also making a usb-c uart now that is slightly longer :)

        We still have tons of original USB-UART adapters. The new adapter will be sold from the next year probably. ;)

        Oops, sorry for giving you away! And thanks for the uart adapter ;)

        after they release the usb-c version the source will be updated. :) There will still be a lot of the original around for awhile.

        Nice, I've just been wrapping a piece of tape around it.

        Was it duct tape? :D

            Painters tape, I got a few minutes free this evening and ran a couple off.

            This silver filament I have is terrible but it's what was on the printer and I didn't want to change it.

            Thanks again, the tolerances are nice and tight.Image

            @rooted, thanks for the feedback and photo. It looks good and like mine, which verifies for me that the default tolerences are good. One of my uarts fit nice and tight and the other was snug but not as tight as the first. I didn't know how representative they were but, the component pins that go in the slot in the bottom can be bent a little to tighten up the bottom piece's fit. I don't think it will be necessary for most because I already biased the slot location slightly in the design.

            They were both tight but it's more due to the defective material I used, it has hard bits of something embedded in the filament that wreaks havoc on tolerance and finish.

            PETG is what I prefer to use but what can I say, I was too lazy to put it on.
