Explaining Somethinng on Instagram: "When two smooth surfaces interface, the lack of microscopic "teeth" results in low lateral stability, causing components to slide or vibrate out of alignment. This is the High-Tack Elastomeric Interface, a precision modification that uses the thermoplastic properties of hot glue to create a customized, high-friction insulating gasket that locks parts in place while dampening mechanical resonance. The critical step is the cross-hatched surface texturing. Inste
