Bolt/nut with hidden compartment

thingiverse

The bolt stands at an impressive 63 mm tall, its sturdy hex-nuts firmly anchored to the bottom. Beneath the cap lies a cleverly designed extra compartment, waiting to be discovered. Printed with precision and care, this model boasts a fine resolution and a robust 20% infill, rendering support material entirely unnecessary. If you're as thrilled about it as I am, don't forget to show your appreciation by giving it a like!
