<p>I would like to print a custom version of something akin to this rugged case that was originally created using injection molding:</p>
<p><a href="https://i.stack.imgur.com/oL8JW.jpg" rel="nofollow noreferrer" title="ea weather proofed tablet with over-molded rubber"><img src="https://i.stack.imgur.com/oL8JW.jpg" alt="ea weather proofed tablet with over-molded rubber" title="ea weather proofed tablet with over-molded rubber" /></a></p>
<p>The outside consists of a material that is a bit softer than the main body.</p>
<p>It is used to protect the electronics against drops when the case falls onto the floor.</p>
<p>Unfortunately, I don't know which material this is, and I don't know which method I could use to measure its softness.</p>
<p>I would therefore like to ask if anybody has experience with such a softer outer hull and can tell me which material could be used when I want to 3D print it.</p>
<p>I would like to use this case in a hospital environment.</p>
