<p>Pop the bubbles back and forth.</p><p>The body was printed with PLA and the bubbles were printed with TPU. It works best with Shore 85A TPU but will also work with 95A. </p><p>You can either print a top and bottom and snap them together or print two tops and connect them with pieces of 1.75mm filament.</p><p>Set the TPU bubbles in one side, add glue and put the other side on.</p><p>FCStd (FreeCAD) files included. I had to mess around with the bubble dimensions a bit to get a good result, so if your particular filament doesn't work well it can be easily adjusted. </p>
