STLink Clone to GnuK back cover

thingiverse

After a talk by Gniibe at FOSDEM 2019, I was inspired to try his GnuK firmware. I ordered a couple of STLink clones for me and a friend, and got to work. When you remove the no longer used pins on the back, you're left with a hole in the casing. This print should plug that hole, and allow you to put it on your keyring. It'll clip over the crystal for some grip, but I still recommend glueing it in for extra protection. I designed this in FreeCAD, and uploaded those files too if you'd like to adjust the tolerances. I printed in 0.3mm layers in PETG, but PLA or ABS will probably work too. When printed, remove the old pin header, try to get most of the solder off of the pads. Then put the ring part on the back of the PCB, clip the underside over the crystal, and slide the device back into it's casing. Enjoy!
