I need a small screwdriver to take the plate off my FW to clean out the lint. The screw at the back is very sticky and the small screwdriver that I do have is too tall to fit there, so I am only able to turn the screw about 1/8th of a turn each time. I recall seeing someone post on here a link to a company that sells a sewing machine screwdriver that is about the size of a dime and costs $8-10. I did a search but cannot find the link to it. Does anyone know where I could find this tool?
