Titanium is great stuff, but expensive. I made PCB holder too. Two 
pieces of 6mm rod cut 30mm long. One end of each rod I hack saw a slot 
about 20mm deep. The slots are modified so a 1.6mm PCB neatly slides in. 
At the opposite ends, I drill a centre hole and press fit a length of M4 
threaded steel rod. This provides a stud to fasten to my plastic holder 
with common steel nuts. The two titanium rods then stand perpendicular 
to a small piece of acrylic sheet, which on the opposite side, has a 
handle. The titanium has stood the test of time.


Titanium won't work as an anode. All you'll do is build up an oxide 
layer until it gets so thick, that the voltage required for electrolysis 
will be > 50 volts. i.e you just make an electric heater.

People who routinely do electrolysis in chloride solutions use titanium 
coated with a conductive precious metal oxides. try a google search
