I was successful in repairing these air leakages by casting small amounts of silicone, however, It was accidentally ripped open because I used too much air pressure while inflating it. <\/p>\n\n\n\n<p>I did cast a second part in parallel to repairing that first part &#8211; this time, I used modeling clay to raise the bottom mold edges up (approximately 1 mm) &#8211; which successfully prevented the bottom face to have air leakages but appear to be slightly too thick since now the part doesn&#8217;t inflate towards one direction &#8211; as happened with the first casting of mold C. Additionally, there is one location of air leakage around the opening of the tube &#8211; as can be seen in the documentation video below. The Ecoflex silicone rubber 00-31 that was used seems to have the correct softness needed. <\/p>\n\n\n\n<p>Changes planned for the next mold version:<\/p>\n\n\n\n<ul><li>Reduce the part&#8217;s leangth and number of cavities.<\/li><li>Slightly increase the thickness of the bottom part, while maintaining the unequal ratio between the top and bottom parts.<\/li><li>Attempt to extend the mold to the complete structure of Whitesides&#8217;
