You don't find good mentors, good mentors find you. I have had multiple good mentors in my career (both student and work) and I have been an attentive mentor to three people in my life. Your mentors choose you, and it is wrong to think of mentors as ideas/advice machine. Mentors mingle with you depending on your personality, taste, potential, current level, etc. Be yourself. Put yourself in situations and locations where you are more likely to cross paths with potential mentors. Communicate with people more. If you are eyeing someone specific, let them know of your existence, interests. And ask them advice on something specific. Keep the connection if the other party is willing. Mentorship relations that form and evolve naturally are the best ones. And mentorship relations are not one-size fits all. Some mentors are more attentive and more engaging than others. Some relations last for life, some for months. No kind is inherently better than the other. tl;dr: be in places together with interesting people (fully online forums count, too). Ask for advice. Keep the connection. Let a relation form automatically.
