This is a 3D model for printing a buteful charging DOC-station for the Huawey Watch GT3 smart watches. This model was printed and use for Watch GT3 with stock charging cable. Fit very well. Use default printing orientation. Infill density is not really important, but solid model will have highest weight what is a good reason for this device. Back cover can be screwed by 2x6-8 mm screws.
