@unchartedcustoms: Do you want to improve your cutting power and make full wrap tumblers easier in the Thunder Bolt? The 4” lens is the answer. The lens kit comes with everything you need to swap out the standard lens in just a few moments. Installing this will boost your power and allow for a little more tolerance being out of focus on uneven surfaces like tumblers. With multiple lenses on hand, my Bolt is now ready for peak performance. #maker #laserengraving #artist #thunderlaser #custommade #wooddecor #woodworking
