Yes, that is the way I fish them. Or you can fish them under a balsa float. I use them for crappie. They are very light jigs. A good hook to use is the Matzuo Sickle hook if you have any or you can get the Mustad or E.C version of that hook.
My temp tower came out good on that if I remember correctly I print hotter for the better layer adhesion. I don’t think that matter much for the molds though.
