PCB Stand Off Tool
thingiverse
I made a 3mm 3.5mm and a 4mm stand off release tool, just simply slide the correct size onto your stand off and gently pull back on the PCB to free the PCB from the stand off, no more using pliers at awkward angles and trying to press the release in to free your PCB. Just remember as with anything that doesnt want to move, DO NOT FORCE RELEASE OF THE PCB OR DAMAGE TO THE PCB MAY OCCUR, see what is going on, it should just simply slide away from the PCB. If you would like a different size just let me know, I made these based on the 3 common sizes I have ran across.
