Pinwheel

注意点：底面建议采用八角螺旋，这样在弯折时候比较均匀受力，顶面直线没问题。关于材料建议使用柔韧性较好的材料，比如bambu pla，polymaker pla。补充一种办法，打印完成后，使用热床加热到打印的模型，利用热变形折弯。Points to note: The bottom side is recommended to use octagonal spiral, so that the force is more uniform when bending, and the top side is straight no problem. Regarding the material it is recommended to use a more flexible material, such as bambu pla, polymaker pla. To add a way, after printing, use the heat bed to heat to the printed model, using thermal deformation bending.
