AR Hammer Block - Takedown pin version

AR Hammer block that uses the takedown pins to retain. prints in about 20 min. you don't need to keep the layer height low as these get dinged up a lot, and don't need to be pretty. I do recommend 6 walls @ .4mm width (or if you using .6mm nozzle you can doe 3 walls) and try at least 25% infill.
