{"product_id":"neodymium-disc-magnets-5x3mm","title":"5mm x 3mm N42 Neodymium Disc Magnets","description":"\u003cp\u003eThese 5 x 3 mm N42 neodymium disc magnets are made for heavier model assemblies that need to separate for storage, painting or reconfiguration. They use axial magnetisation for flat-face attraction and a NiCuNi coating for normal indoor workshop handling.\u003c\/p\u003e\n\u003cp\u003eThis is the upper step of the 5 mm family: a deeper magnet for vehicle turrets, sponsons, substantial weapon mounts and other components that should remain firmly seated when the model is picked up or moved. Its holding force is a calculated, zero-gap reference figure of 650 g, while the sideways shear estimate is approximately 90 g. The extra depth is worthwhile where the bore is already fixed at 5 mm and the part has enough internal material to support a stronger joint. It is less appropriate for thin bases or panels, where the required cavity would remove too much material.\u003c\/p\u003e\n\u003cp\u003ePrepare a 5 mm opening with a 3.2 mm-deep recess, or start with a 5.1 mm hole when designing the socket into a 3D print. Test the fit and polarity before gluing. Key a smooth resin surface if necessary, apply CA adhesive along the side wall and allow it to cure fully before separating the parts. For turrets or long assemblies, add a locating feature so the magnet holds the component down without being the only thing preventing rotation. Pack options are 1, 10, 25, 50 and 100.\u003c\/p\u003e","brand":"Hobby Heaven","offers":[{"title":"1","offer_id":37686925263037,"sku":"MAG\/D5X3\/1","price":3.35,"currency_code":"CAD","in_stock":true},{"title":"10","offer_id":37686925295805,"sku":"MAG\/D5X3\/10","price":4.0,"currency_code":"CAD","in_stock":true},{"title":"25","offer_id":37686925328573,"sku":"MAG\/D5X3\/25","price":4.97,"currency_code":"CAD","in_stock":true},{"title":"50","offer_id":37686925361341,"sku":"MAG\/D5X3\/50","price":6.56,"currency_code":"CAD","in_stock":true},{"title":"100","offer_id":37686925394109,"sku":"MAG\/D5X3\/100","price":9.93,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/9583\/4503\/files\/5x3mmHero1.jpg?v=1785937192","url":"https:\/\/hobbyheaven.org\/en-ca\/products\/neodymium-disc-magnets-5x3mm","provider":"Hobby Heaven","version":"1.0","type":"link"}
