A simple, yet confusing modern vase.  I've included a regular and wide variant.

Instructions:

Please print with regular supports enabled, I had mine set to 20 (though it shouldn't matter much).  It should only need supports within the floating region of the model. In my tests a couple parts of the supports it attached to the overhang strung off, but it did not affect the end result.

Both of my test prints were done at full scale, though I'd assume they'd do just as well scaled down.

Note: Please slow down your overhangs depending on what your printer is capable of. The majority of the vase was designed with using as little support as possible, but they do get a bit steep toward the top. Mine has no issues but I did print it fairly slow (For a Bambu P1P anyway). Also avoid using outer/inner/infill printing patterns as my tests showed that didn’t work well.

I've included a file for a circular flower guide that helps sell the illusion of the flower(s) standing straight up.  The holes may not fit your particular fake flowers, but feel free to bore them out a bit if needed.  The guide fits in semi tight if pressed down enough, but was purposefully left loose so as to not become stuck once inserted.  Feel free to dab a bit of hot glue on the edge of the insert to keep it in place.

Simply slide your flower(s) through the guide, then into either the long cavity or short cavity (if your stems are short), then insert into the vase.  Then just bend your flowers so they stick straight up and you're done!

Note: Using a lot of wide stemmed flowers may take some trimming/stripping of the plastic.  The example with the 4 sunflowers in my photos took a bit of trimming to get to fit well.
