I enjoyed ThunderMuffin's SD card toaster idea, and made my own design. 2 or 4 slice versions, full size SD cards.
There's a hole on the bottom plate for a round rare earth magnet
I added a pair of wings. Because After Dark.
Wings should not need supports if printed in the orientation in the STL-- However, they may be fragile during printing due to the small contact area with the buildplate. Brim is recommended. Also, I positioned them so they just barely touch. If you print with no retraction, the stringing will act as cross supports and help the two wings support each other while printing.
Painted with Valspar silver metallic spray paint.
glue the wings on using their flat disc areas.
