The terminals on the Mean Well LRS-350 series PSU are not covered. This fixes that. It will not prevent short or shocks when poking around with a screenshot driver or other conductive items, but at least you won't accidentally touch them.
I tried to be inclusive; there is a 240v, 230v, 110v, "Danger!" and a blank protector. (The last one in case you want something else written on it)
Insert the top site first, then click in the bottom side.
DISCLAIMER
I am not responsible for you getting shocked; always power off and disconnect the power lead before opening up the electronics case. Just because I do not listen to my own advice does not mean that you should not either!
(Phil Collins said it; "Just do as I say, don't do as I do." and James Hetfield as well; "You can do it your own way, if it's done just how I say")
Consider yourself sufficiently warned ;)
important note;This is the Mean Well version of the guard, not to be confused with the Landy version. This one will NOT fit the stock Ender 5 PSU. For Ender 5 stock PSU, see https://www.thingiverse.com/thing:4761289
