Floating Cup improved, good balance

This is an improvement on the rather popular "Floating Cup (smoother look, foolproof assembly)", https://www.thingiverse.com/thing:3689716 . See that Thing for notes and directions of how to print it, assemble it, prop it up during gluing, etc. Some people were having problems keeping theirs balanced upright and not falling backwards. That might be because they didn't look close enough at the drawing that shows how the the "stream" must be angled (see the picture included here with the vertical red line drawn on it) or the different infill amounts needed. But even when done well, the model wouldn't withstand a bump or a shaking table. So this one includes an open pocket in the bottom of the "splash" design so that a weight can be glued in there. The weight I used and designed around is a stack of 3 "carriage bolt washers", 2 inch outside diameter and 1/2 inch inside diameter. There is probably a metric similar washer but hardware stores here don't carry much metric. You could alternately fill the pocket with lead shot or weights and then fill with epoxy to make the base heavy. Because there also has been some difficulty keeping the cup glued to the stream (particularly after one falls over!), the stream STL has also been modified with a number of small holes in the surface area where it gets glued to the cup. This allows the glue to grab the stream much better. Holes were not added to the cup, to allow you to rotate the cup handle to where you want it when you glue them together. If you want, you can drill some short, shallow holes into the side of the cup in that area as well. The example pictured here of course has a swimming duck again, and was printed in gold. There are also photos of it standing on several "tensegrity tables" to grab more attention. https://www.thingiverse.com/thing:4292334 https://www.thingiverse.com/thing:4335706
