Aeldari Guardian Defenders and Storm Guardians both build from the same plastic frame, with one squad member mounting a heavy weapon platform. The Support Weapon Battery shares the chassis but swaps in a D-cannon, vibro-cannon, or shadow weaver. A few well-placed magnets let you switch the platform crew between scatter laser, shuriken cannon, missile launcher, bright lance, and starcannon, and let one Support Weapon kit cover all three battery profiles.
Guardian Heavy Weapon Platform & Support Weapon Variant Swap
For the Guardian heavy weapon platform, magnetize at the gun mount where the barrel assembly meets the cradle. A 2mm x 2mm disc magnet pair on each side gives you a clean swap between the five Guardian platform weapons without flexing the slim Aeldari joins.
The Support Weapon Battery uses the same approach: magnetize the upper barrel housing where the D-cannon, vibro-cannon, and shadow weaver tops attach to the lower carriage. One carriage covers all three battery types in your list.

Base Magnets: 25mm Guardians, 60mm Support Platform & Miniature Case
Guardian Defenders and Storm Guardians ride 25mm round bases. Use the Flush-Fit Base Magnets - Medium 4.5mm x 2.2mm so they sit flat against a steel transport tray.

The Support Weapon platform uses a 60mm round base. The Extra Small Flat Magnetic Flight Stand works as a posable magnetic anchor for the platform crew and gun.

Prefer to skip drilling on the 25mm bases? The premagnetized bases drop straight into your assembly with the magnet hole already preset.

For an even faster basing route, the Peel & Stick Inner Base Magnets press into existing bases with no drilling.
