You probably have an Atmel/Microchip ATF15XX-DK3 CPLD programmer board at home, but are a bit frustrated that it's basically a bare board that's a little bit untidy (and vulnerable to damage.)

Well, fear not, print this base and you'll be good. The board screws to the threaded mounts on the base, and the USB-JTAG adapter module can be affixed into the corresponding well on the top right (I just used a gluegun to fix it down.)

It's a super simple model, so nothing special to say about printing it.
