Replacement slider knob covers designed specifically for the DOD FX40-B equalizer. Existing options on the market are scarce and often overpriced, so I created these as a practical, affordable alternative. The design is slim and closely mimics the original aesthetic, fitting the unit perfectly without modification.

Portable air conditioners are notoriously awkward to vent. Most window kits look messy and feel like an afterthought. This adaptor offers a cleaner solution — designed to mount directly onto a standard louvre vent (260mm × 90mm) and snap onto the 150mm exhaust pipe coupler that typically ships with portable AC units. The result is a tidy, purposeful finish that beats any generic window kit.
