These are storage and organization products. They are not certified safes, not safety equipment, not lockable security containers and not fire-rated containers.
Adults only: you must be 18 or older to purchase from the M&D Storage & Organization category.

ViewMaterials & manufacturing
Designed & 3D printed in USA
Every product is designed and 3D printed by SKThreeD in our Florida workshop, then finished and checked by hand.
- PETG — rigid, UV resistant and weatherproof. Used for hitch covers, boxes and organizers.
- TPU — flexible. Used for seals, gaskets and flexible parts.
Our print capacity
From small precision parts to large single-piece builds.
Largest single part

(13.8 × 12.6 × 12.8 in)
Smallest detail parts

Bigger than that? We split parts into modules and join them — just ask. This is a machine build volume, not the recommended size for a custom hitch cover. Request a custom part
