Wi-Fi (or) transistor radio signal strenth booster

thingiverse

Cover your Wi-Fi router's antenna with aluminum foil and lay it over to block the signal. Print 2-3 units if you have multiple antennas on the same router. Dimensions: * Width: 2 inches * Depth: 1 inch * Height: 3 1/2 inches This design is compact, but you can easily extend the aluminum foil on each side by overlapping the top or increase its height by overlapping the sides. I used PLA with a layer thickness of .3 mm and an infill density of 5%. An updated version with a brace on the bottom is also available as a separate .stl file, which may improve stability when resting over the antenna.
