Description

An ultra-compact, passive (non-motorized) keychain water filter cap concept designed for standard single-use plastic bottles. Features a Ø32 × 44 mm bead-blasted 6061-T6 aluminum outer shell with a continuous R2.0 mm top fillet, a recessed flip-top lid with a spring detent, a passivated 304 stainless steel and platinum-cured silicone internal water path, and a tool-free quarter-turn bayonet filter carrier.

Build notes

Includes both nominal metal production STEP assemblies and +0.15 mm clearance-adjusted STEP/STL exports for SLA resin fit-check printing. Hardware envelope references AS568 platinum-cured silicone O-rings (Marco S1083 series), a Ø1.5 × 10 mm 316 stainless hinge pin, a Ø25 mm media pocket, and a provisional miniature silicone umbrella air-return valve seat (Minivalve UM045.002 reference). Dry-fit architecture and packaging prototype only—filtration performance, pressure retention, and drinking-water suitability require independent physical validation.
