Luckily for you and I, there is no real need for a collectible guide as once you obtain the first tier of the Smart skill, all of the blueprints will be shown on your in-game map. There are over 100 blueprints within the game, but you will need all of the weapon blueprints in order to obtain Duct Tape Master. The blueprints will come naturally through story progression and by retrieving them from the environment, so pick them up whenever you see them nearby in order to cut down on the amount of running around you'll need to do later.
