And crap. I've been building towards a custom keyboard that fits in a TEX CNC case and my numbers don't line up to the ones on the site at all. Worst part is the 3d printed prototype totally fits, but I'm at least 3mm off of both Swill's and JD's numbers, and the effect is cumulative (I had to set the unit length to be 19.2 in order for there to not be a ton of slop). I got some tough decisions to make before I get a plate cut...
Hmmm, that's strange. Send me what you have, and I can check it for you. Maybe we can figure out what's going on.
Ya, I can take a look too. Just send us the files.
Hey thanks guys, it's much appreciated.
so I made a little album here:
http://imgur.com/a/vjZZIthe first image is the three plates, JDCarpe's DXF in the middle (which is reversed for some reason, but you can see the outline) and Swill's exported STL at the top. I've got around a 3mm difference on you guys, which sounds trivial, but it's across the whole board, so the further right screw holes don't line up at all. The plate I printed on my 3d printer fits the case though in both dimensions really well, which is a fair stroke of coincidence if the sizing is wrong, since the key units are still square - I just upped the side's length from 19.05 to 19.2 and slop on both sides of the plate disappeared perfectly.
The print also seems to be pretty dimensionally accurate, as I have the total length coming in at 288mm, and the case seems to be around 277.5mm or so in the third picture.
my designs aren't proprietary or anything so I'll attach the STL and SCAD here but if we want to continue this elsewhere in order to not gum up the thread that's fine too. Where did you get your numbers from JD? maybe the tex case has extra slop around the edges
