Well all the casio 445s have 'em but am I missing the advantage of them?
With or without whats the difference?

nice to have for a lab build or possibly a pointer for shorting protection.

You'd probably be better served with some heatshrink tubing. I know I removed the spacer from my own diode before using it.

I remove my spacers too i think theyre annoying :D
I cut down the leads to 2-3mm, if id let the spacer there it would melt anyway.

They are nice to make sure your pins wont cross but they should not melt, if you solder right your iron is only there for 1second and the plastic is a bit heat resistant.
It is up against the laser while it runs and has not turned into a puddle so it has to be.

I agree... there is no real use for those Casio 445nm LD Red spacers...
I also remove them and I also use Heat Shrink on each pin after making
my connections..

Heat shrink the connections. All these add is more space between the diode and the solder joint. They are not needed

Peace,

if you move the pins enough to touch they'll break anyways. My 445 died because a pin snapped off, and I barely applied any pressure. I was just feeling to see if there was any resistance before trying to slide the spacer off. I say keep it on. Less chance of pulling a pin off.

If it broke off with barely applied pressure, the pin had already been bent back and forth several times before you got it. I get repair jobs in where the owner had twisted off the wires by disassembling their laser incorrectly. The pins are even twisted together. Even these are OK about 90% of the time. I just untwist them and re-solder the connections (then I heat shrink them ;) )

I can repair it, it's just not stable enough to put in a hand-held now. That's ok, though, I was gonna try to resolder it (again) and just glue the wires in place further up on the heatsink so that they can't move but I can still resolder it when it breaks.
