Float My Caps, a 3D-Printable Floating-Cap Configurator

Field notes

The configurator varies wheel-fit geometry while keeping the central mechanism fixed, including two bearings, a spacer, shaft, clips, counterweight, and cover. It exposes measurements such as face width, back clip width, retention depth, and a 3 mm counterweight gap before producing five STL files with dimensions and a validation report. The page also tells users to inspect supports, test bearing fit and free rotation, and verify wheel retention themselves; the size variants are explicitly described as experimental.
