Two perfect pieces that compliments each other to create a heart, with a hole for use as keychain or necklace for the couple. You can use it for asking marriage to your couple, maybe it works! 1.) Download STL file for printing (Include 2 pieces) or .SCAD file for modify pieces. (Code is a mess, i'm newbie) 2.) Print pieces 3.) Invite your boyfriend/girlfriend for dinner 4.) In the middle of the dinner, give him/her his/her part of the heart and ask for marriage. 5.) If he/she says "Yes", join both pieces of the heart. (If he/she says "No", take both pieces and go look for another couple! Haha) 5.) Be happy :)
