I liked the original thing, but wanted to add a mini toggle switch (as shown in the third picture) for my auto mouse clicker device. The original thing wouldn't load in 3d builder, slic3r or netfabb, but repetier was able to properly load it & re-export the file, so I was able to load it into tinkercad for the quick edit. Fit is perfect for my implementation, that being said if your device isn't constructed exactly like mine it may be too snug a fit without scaling.
