I have merged butterfly by ericchf and made it thinner. Bottom portion is 1mm and top is 0.6. Set all layers to be 0.2mm high (including first layer), pause at the start of 6th layer. If your nozzle is 0.4mm print at 105% size in order to make sure no walls are skipped.
Please post pictures if you make one.
It is possible to bend the wings. Using a lighter, heat the base of the wings. Not too much though, moving lighter on the line for 1-2 seconds is enough. After heating, immediately push down the butterfly on table and gently pull the wing up. Keep the middle section down to have a straight surface to fix it on wall. You can glue a magnet too!
Instead of overdoing the heat prefer repeating multiple times. Wait for a minute between applications.
