4:1 gearbox

I made this in Autodesk fusion to help stir my coffee because using one of my hundreds of wooden coffee sticks was too hard. It uses Helical gears because they mesh better. I also used 21030 Synthetic grease on the teeth of the gears before gluing the lid on. took a bit to work in but now they spin freely with little resistance. Both shafts are meant to turn clockwise from their perspective. I didn't include my mixer attachment because it was just some model I found and modified to fit.
