Based on the measurements from the Daylight website for the basic dimensions plus my calipers for button and hole locations, etc. I've done some small test prints to confirm the basic dimensions, which came out bang on with my (X1C) printer.

I created this with the intent of making a case for it, as there are none available anywhere at the time of uploading this (Daylight themselves plan to release some cases later this year, but no one else seems to know this computer exists). Unfortunately, my printer isn't large enough to print a case in one go, so I need to get creative to figure that part out, but I figure the device model might be useful by itself so I'm uploading that now in case someone else has a need for it.

Let me know if you'd like different versions of it (i.e. without the holes, with holes extended out, etc) or if you have any feedback I can use to make a better version.
