Turn your Origin-Zero Mecha into a fully modular loadout platform.

This backpack clips onto the Origin-Zero Mecha using the built-in clip mount, then gives you a brick-compatible surface on both sides. It has studs on top for stacking plates, cannons, wings, radar, “shoulder” builds, etc as well as anti-stud pockets on the bottom so bricks/plates can snap in from underneath too (super solid for weapon mounts and chunky modules).

It’s basically a “blank canvas” backpack: build anything you can imagine, swap it in seconds, and make your mech look completely different every time.

A couple important print notes: this has been tested with real bricks on a PLA print (tight, snappy fit). PETG prints may be slightly different size and may need slight scaling/tolerance tweaks depending on your settings because this design uses tight tolerances for a strong brick grip.
