Tactical Aquarium Wiper

thingiverse

Recently a special item premiered to clear fog from goggles during Airsoft or paintball matches without removing them once. Unfortunately, it's too pricey for my tight budget, but the concept is quite clever. It utilizes magnets similar to those found in aquarium glass cleaners that let you clean the interior without touching the glass. So, why not create one yourself? It requires a 2mm neodymium round magnet and a 4/5mm neodymium square magnet for the pegs. These are superglued inside with felt cutouts covering their contact surfaces. My friend Mikołaj designed the models I'm using, but I need to brush up on my Tinkercad skills to get accurate dimensions.
