LS-OCMA6BL70 open and close mechanism design plan 3D print model

Some parts can be laser cut, and some parts can be 3d printed. The center hole can be open or close gradually. When it is near open to max, there may be a dead point, so you need to do some hand work to make it work well. STEP format files are included. Ignore FBX and OBJ format files, they are only used to meet the platform's requirement.
