{"product_id":"neodymium-disc-magnets-3x3mm","title":"3mm x 3mm N42 Neodymium Disc Magnets","description":"\u003cp\u003eThese 3 x 3 mm N42 neodymium disc magnets are built for jobs where the opening must remain 3 mm but the joint needs as much holding force as that footprint can provide. The NiCuNi coating protects the magnet during normal hobby use, while axial magnetisation places the poles on the flat faces for clean face-to-face contact.\u003c\/p\u003e\n\u003cp\u003eThis format suits torsos, heavier miniature arms, weapon mounts and compact assemblies that cannot accept a wider bore. Its calculated, zero-gap pull reference is 270 g, with sideways shear estimated at approximately 40 g. The extra depth gives more hold than the shallower 3 mm options, but it also demands a substantial socket, so it is most useful when the part already has enough internal material to accept it.\u003c\/p\u003e\n\u003cp\u003eDrill with a 3 mm bit and prepare the recess to 3.2 mm deep. For a 3D-printed component, begin with a 3.1 mm hole. Keep the base of the socket flat, confirm polarity before gluing and use CA adhesive along the side wall so the magnet cannot be pulled free when the joint is separated. Packs are available in 1, 10, 25, 50 and 100 magnets.\u003c\/p\u003e","brand":"Hobby Heaven","offers":[{"title":"1","offer_id":37686797861053,"sku":"MAG\/D3X3\/1","price":3.39,"currency_code":"AUD","in_stock":true},{"title":"10","offer_id":37686797893821,"sku":"MAG\/D3X3\/10","price":3.87,"currency_code":"AUD","in_stock":true},{"title":"25","offer_id":37686797926589,"sku":"MAG\/D3X3\/25","price":4.85,"currency_code":"AUD","in_stock":true},{"title":"50","offer_id":37686797959357,"sku":"MAG\/D3X3\/50","price":6.31,"currency_code":"AUD","in_stock":true},{"title":"100","offer_id":37686797992125,"sku":"MAG\/D3X3\/100","price":9.22,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/9583\/4503\/files\/3x3mmHero1.jpg?v=1785936532","url":"https:\/\/hobbyheaven.org\/en-au\/products\/neodymium-disc-magnets-3x3mm","provider":"Hobby Heaven","version":"1.0","type":"link"}
