Obelisk & Tesseract Vault Magnetization Kit
Couldn't load pickup availability
Recommended
Build the Necron super-heavy once and field it three ways. This kit magnetizes the Games Workshop Obelisk and Tesseract Vault plastic kit, so the same model opens from a sealed Obelisk into a full Tesseract Vault and the Transcendent C'tan shard lifts in and out of the cage.
What this kit does
- Opens and closes the four pylons and outer walls to switch between the Obelisk and the Tesseract Vault.
- Lifts the Transcendent C'tan shard out of the cage and stands it on its own display rock.
- Removes the Wraith warden tail so the shard clears the cage cleanly.
In the kit
- 18 of 5mm x 1mm N52 disc magnets for the core cables, pylon extensions, and the C'tan cage.
- 8 of 5mm x 2mm N52 disc magnets for the pylon branch sockets.
- 8 of 5mm x 1.5mm N52 disc magnets for the wall shelves.
- 3 of 6mm x 1mm N52 disc magnets for the C'tan feet, the display rock, and the cage floor.
- 1 custom 3D printed display rock.
- 1 pre-cut acrylic flight rod for the standalone C'tan display.

Compatibility
The Games Workshop Obelisk and Tesseract Vault plastic kit, which also builds the Transcendent C'tan. Sized for the current plastic kit, 10th edition Necrons.
Install
Difficulty 4 of 5. Drilling required with 3mm and 5mm bits in a large pin vise. This is one of the largest plastic kits in the game, so plan an evening for it.
Tips
- Keep all eight wall corner halves separate until each shelf magnet is set. Building the walls first makes the drilling harder.
- Save a few of the kit's scarabs to cap any hole you drill through, then seat the magnet flush against the scarab.
- Run a flat needle file across the C'tan feet and both ends of the acrylic rod so the glue grabs.
