About this 3D model

AMAO elder brother designed the Dragon Playing Pearls model, the original model using hand-held mode, time-consuming and labor-intensive and rotation is not smooth (at least I am so), so I drew two small parts, using Bambu electric components as the power of the model, freeing hands. Does not need to adjust the elder brother's original model can be used, just print down, a model through the original model of the buckle fixed motor (pull out the original model buckle), another model link motor power, can be achieved. Tips: if you print the elder brother's original model rotation is very card, then you need to grind the gear hole, and it is best to spray some lubricant on the friction surface, especially the 11 pillars friction place!
