Flopped set EP, check called flop

Question is just about my flop play.

I decide to check call the flop because the board was so dry. The Th was pretty much the worst card in the deck out of all of them, so I decided to check call down after the turn.

As the PF raiser, am I better off just simply Bet/3Betting this flop or is my line ok?
