I wouldn't even make a 3bet that small with 100BB stacks
I really depends how wide your 3bet range IP is. If you 3bet only QQ+ then sure you have to protect your hand from set. When your range also includes AQ+ and some other hands (SCs etc) then setmining is not profitable after 3bet to 3$ in NL25 100BB game.

If you're going to 3bet at all preflop make it $4.50
What hands call you that you beat if you make it 4.50?
3bet size is also correlated to you ability to play good postflop. As OP doesn't find a fold postflop then he might be better off raising more preflop (and tightening 3bet range to JJ+, AK).
