Click a character to roll to it. Like the real spool it only turns forwards. You can also type a key while this tab is open. Space = play/pause, → = step. Set the speed to 1–2 flaps/s to watch each flap fall.
Physical flaps (as printed)
Numbers match the objects in the 3MF. Left: front face. Right: back face, seen from behind. Hinge = bottom edge. “Face-down” flaps print with the front on the bed (Print plates → Surface finish).
Export
Downloads flaps.3mf. Open it in Bambu Studio. The firmware list and config.yaml are on the Firmware & config tab.
Build plates
Each character is the front of one flap plus the back of the previous one, so alternate flaps print face-down to give both halves the same finish.
Same 4×5 grid as the export. Grey corner = bed exclusion zone, dashed = prime tower, ↓ = printed face-down.
Sort printed flaps
Firmware flap list
Replace flaps[NUM_FLAPS] in scottbez1 firmware/src/config.h. Also written to output/firmware_flaps.h on export.
