Here's my hinge design! It's a little hinge that is tightened with a m3 bold and a nylock nut. It works realy good after a little wear and a rdrop of oil. Pretty strong too!1) rotate the parts till they ley flat 2) Print both parts with .1 or .2 layer and 100% infill. 3) Some of you may need a little brim for the hinge to stick to the bed. 4) Sand the rond part verry lightly 5) insert the nylock nut (carfully!) 6) Assemble it Enjoy! hope to see pictures of your makes =)
