Rose (printed flat) Rivet style

I've posted a Make that explains a lot, but this is the stem, flower (moded original), and.. back? That I just whipped up on tinkercad. It's nothing special but it what I used. Just put everything together flat, then use aluminum foil as a heat shield, heat the top of the stem, then press it down with more foil (Don't Burn Your Fingers!!). Then you can use the same foil to shield the petals you aren't working on, heat and bend them individually. I did the same for the stem. Heated it in a few spots and bent it. Just don't heat it too much or it will fold in. I used 20% infill to help with that.

Play around with the amount of heat. Too much they melt, not enough and they don't bend. There is a HUGE margin of error so no worries. Again, DON'T BURN YOUR FINGERS!
