Where can I find a screwdriver for an Etch-A-Sketch Animator?
A Tri-Groove might work, but I don't think the driver is going to clear the outer plastic housing. If anyone knows where I can find a bit to remove these, I'd appreciate the help!
As far as advice on improvised removal techniques: Dremel techniques or any kind of "use a pair of dikes" technique won't work here because the screw is recessed by about 1.5cm in a channel that is maybe 1mm wider than the screw head. I'd like to avoid "Melt a pen" techniques to avoid damage to the casing and/or getting a pen permanently melted into the shaft. Besides, with the size of these screws (1/4 inch head?) and the age of the device, I doubt a Bic pen will have the torque necessary to pop the screws. (Keeping that under my belt as a last resort, though.)
Links to a recommended Tri-Groove set with plenty of differently sized bits would be awesome as a second to last resort. There's so many and I'm a bit out of my element.
