Lightweight Top Module for C4 Dyno Collar

Lightweight Top Module for C4 Dyno Modular Freediving CollarThis model is a custom lightweight add-on designed for the C4 Dyno modular freediving neck collar.Its purpose is to replace the original top weight with a much lighter component, reducing the load on the neck while maintaining perfect compatibility with the modular system.The geometry follows the same attachment pattern as the standard Dyno weights, ensuring a secure fit while improving comfort during long pool or depth sessions.Ideal for freedivers who prefer a balanced setup but want to minimize neck strain.Printed in lightweight materials (PLA-CF, PETG, PA12, etc.), this piece helps maintain proper trim without the excessive front load of traditional weights.
