+To approach the security of the data and power connections passing through the IHSM's unprotected shaft,
+\textcite{gotteCantTouchThis2022} list some shielding methods that use a independently rotating secondary tamper sensing
+mesh on the inside of the primary mesh, located right next to the primary mesh's axis opening. This secondary mesh
+makes accessing the payload using probes inserted through the shaft much more difficult.
+\textcite{gotteCantTouchThis2022} only present conceptual drawings of these schemes, and focus on electrical signals. In
+this paper, building on these concepts, we present mechanical designs of three variations of an IHSM pass through that
+are adapted to the limited bending radius of optical fiber: A simple disc cover, offset labyrinth meshes, and
+interlocking gear meshes. We present a mechanical prototype of our offset labyrinth mesh design.
