To get this to function smoothly, your 3D model needs to be designed with "Mechanical Clearances." If you model everything at the exact size of the bolt or watch, the parts will be fused together and won't move.Here is the master specification guide for placement and sizing.1. The Core "Swivel" SpecificationsThis is the vertical pivot that allows the bottom two watches to rotate left and right.FeatureX/Y PlacementZ-Height (Thickness)Diameter (mm)Main Pivot HoleExact center of the bottom chassisThrough all layers3.2mmNut Trap (Hex)Bottom of Wrist Cradle2.6mm deep6.0mm (flat-to-flat)Friction WasherSandwiched between Cradle/Chassis0.5mmID: 3.2 / OD: 7.0Critical Placement: Center the pivot exactly at $(X: 15.1, Y: 12.6)$ relative to the F-91W module. This ensures the weight is balanced and the watch doesn't "swing" awkwardly.2. The "Flip" Hinge SpecificationsThis is the horizontal hinge that allows the top watch to open like a lid.Hinge Ear Width: Each "ear" on the bottom chassis should be 3mm to 4mm thick.Hinge
