3mm x 1mm N52 Round Magnets — “SprueDude Spec”

Dial-in swappable weapons, safe transport, and click-perfect basing. These 3×1mm discs are cut to fit the magnet wells in Wargames Atlantic Dual-Use Bases—drop one in the base and one in your tray or storage, and your minis won’t flop around anymore.

Why these magnets?

• Right size, right fit: Designed around the 3×1mm recess molded into WGA’s Dual-Use Bases, so you don’t have to guess or re-drill.

• N52 grade punch: Strongest commonly available neodymium grade, perfect for weapon swaps, backpacks, banners, and basing without needing bulky magnets.

• Hobby-proven gluing: Bonds great with thin CA (super glue) on clean, scuffed surfaces; use epoxy when you need gap-fill or extra toughness. (Pro tip: lightly cross-hatch the magnet face before gluing.) 

• Nickel (Ni-Cu-Ni) plated: The standard hobby coating for corrosion resistance and smooth seating in plastic.

Use cases

• Interchangeable weapons & loadouts: Arms, backpacks, shoulder options, vehicle turrets.

• Basing & movement trays: Pair base magnets with metal trays or magnet-catch recesses for rock-solid unit movement and transport. (WGA’s own trays (coming soon!) are built around 3×1mm magnets.)

• Storage & travel: Stick to toolboxes, cookie sheets, or magnetic shelves without foam-cut chaos.

Quick how-to (30-second install)

1. Drill or seat: Most plastic parts take a 3 mm bit (⅛") for a flush pocket; WGA bases already have the recess. 

2. Prep: Degrease the magnet, then lightly scuff the gluing face.

3. Polarity check: Stack a few, mark one face with a sharpie, and keep that “mark-to-mark” across all parts to avoid the dreaded repel situation.

4. Glue: A drop of thin CA for tight fits; 5-minute epoxy if the pocket is loose or you want extra abuse resistance.

Specs

• Size: 3 mm diameter × 1 mm thick

• Grade: N52 neodymium (high strength)

• Coating: Ni-Cu-Ni (nickel) for corrosion resistance

• Magnetization: Axial (through thickness) — ideal for disc-to-disc seating in sockets.

Safety notes

Neodymium magnets snap together fast—keep away from electronics, kids, and wandering hobby knives. Don’t heat-cure near them; above ~80 °C they can lose strength. 

SprueDude Tip: Grab a stack—once you start magnetizing, you’ll end up doing every arm, banner, and turret you own. (Your future self says thanks.)
