{"product_id":"neodymium-disc-magnets-3x2mm","title":"3mm x 2mm N42 Neodymium Disc Magnets","description":"\u003cp\u003eThe 3 x 2 mm N42 disc is the general workhorse of this small-format range, balancing a compact footprint with enough depth for regular figure conversions. It is NiCuNi coated and axially magnetised for flat-face connections between interchangeable components.\u003c\/p\u003e\n\u003cp\u003eUse this size for arms, equipment, backpacks, light turrets and basing setups that connect a miniature to steel paper. It shares the 3 mm drilling diameter of the shallower 3 x 1 mm disc but provides a calculated, zero-gap pull reference of 210 g. The estimated sideways shear is approximately 30 g, so the joint should be arranged to resist direct separation rather than relying mainly on sliding friction. For many 28–32 mm projects, this is the practical middle ground between tiny weapon-swap magnets and larger fittings intended for heavier components.\u003c\/p\u003e\n\u003cp\u003eDrill a 3 mm socket to a depth of 2.2 mm, or begin with a 3.1 mm hole when designing the recess into a 3D-printed part. Check that the magnet sits below no paint or glue layer, confirm its polarity against the already fitted side, and secure it with CA glue. Allow the adhesive to cure before pulling the pair apart. Pack options are 1, 10, 25, 50 and 100 magnets.\u003c\/p\u003e","brand":"Hobby Heaven","offers":[{"title":"1","offer_id":37686781411517,"sku":"MAG\/D3X2\/1","price":2.39,"currency_code":"USD","in_stock":true},{"title":"10","offer_id":37686781444285,"sku":"MAG\/D3X2\/10","price":2.51,"currency_code":"USD","in_stock":true},{"title":"25","offer_id":37686781477053,"sku":"MAG\/D3X2\/25","price":2.73,"currency_code":"USD","in_stock":true},{"title":"50","offer_id":37686781509821,"sku":"MAG\/D3X2\/50","price":3.08,"currency_code":"USD","in_stock":true},{"title":"100","offer_id":37686781542589,"sku":"MAG\/D3X2\/100","price":3.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/9583\/4503\/files\/3x2mmHero1.jpg?v=1785936411","url":"https:\/\/hobbyheaven.org\/en-us\/products\/neodymium-disc-magnets-3x2mm","provider":"Hobby Heaven","version":"1.0","type":"link"}
