Stackable SD and CFexpress Type B card holder with cold shoe foot.

The problem it solves:

Memory cards are small, easy to lose, and easy to mix up — is this card full or empty? Which one already got backed up? Digging through a camera bag mid-shoot to find the right card wastes time you don't have, and a dropped card on a dusty set is a real risk to your footage.

This holder keeps your cards exactly where you need them: right on the rig. It slides onto any standard cold shoe using the same foot design as my other cold-shoe accessories, and holds your cards in individual slots sized for a snug, secure fit — easy to see, easy to grab, hard to lose.

Stackable by design:

Need to carry more cards than one holder fits? Just print another one and stack it on top — each holder connects to the next with the same simple interface, so your card storage grows with your kit instead of forcing you to carry a separate case.

Connection 🔩:

The cold_shoe_foot slides into any standard cold shoe — the same foot geometry used across my other designs (RollFlag, Cold Shoe Ball-Joint Camera Arm), so if you've printed those already, you already know how this one mounts.

Cold shoes:

You can find really good cold shoes on kondorblue.com. Some examples:

You can also use a simple cold shoe from anywhere — it'll be compatible with any camera. Or find one on printables.com.

Stack 'em up 📸

Thanks for checking out this design! Print one, print five — stack as many as your kit needs. If you have feedback or ideas for other card types to support, I'd love to hear them. Happy printing!
