i use press my self with a hollow tube, you try to see if it is flat but i would not try to remove the diode once it is pressed in, unless some one has a better method i have always had the diode suffer some damage from trying to remove it once pressed in, either the window on the diode shatters or the top gets caved in when trying to push it back out, if the housing is cheap you can cut along the side but i would not recommend it
