If the gear part is not printed accurately, it will not move well, so print with priority given to accuracy.

If the gear part of the wing holder cannot be printed accurately, it may be better to print it together with the main body to extend the cooling time for each layer.

The left and right gears are very similar, but the shapes are different. It will move even if you make a mistake on the left and right, but the range of movement of the wings will be narrowed.
Please select the gear referring to the image.

If you design the wing parts yourself, the thickness of the wing body should be 0.4 mm, and a protrusion of 0.4 x 1.6 x 5.0 mm should be made for the joint with the holder. (If you have the skill to print with high accuracy, you can use 2.0 mm instead of 1.6 mm.)

Data with "+" in the file name is additional data. It is not necessary if you just assemble butterfly. The custom base is attached for cutting, painting and combining with other materials.
