<p>This print enables you to quickly attach or detach items from your keyring.</p><p>Model requires neodymium (rare earth) magnets:<br><strong>2 x (5mm x 2mm)</strong> or&nbsp;<br><strong>2 x (5mm x 3mm)</strong> or<br><strong>2 x (7mm x 2mm)</strong> or<br><strong>2 x (7mm x 3mm)</strong>&nbsp;<br>(see below for pull strengths).</p><p>Only the 5mm x 2mm has been tested as thats what was on hand. It’s fairly strong, though larger size recommended.</p><p>This has been tested by press-fitting magnets in to each end (pliers help here) But a drop of superglue wouldn’t hurt to help retain the magnets.</p><p><strong>note:</strong> the two halves are not identical - one half the magnet protrudes slightly (Male) and the other half is recessed slightly (Female). This helps them couple properly and prevents wandering sideways.<br><br>Model is a parametric design so iterations of different sizes and magnetic strengths can be tested.</p><p><strong>n50 neodymium magnet pull strength:</strong></p><p>5mm x 2mm = 550g<br>5mm x 3mm = 784g</p><p>7mm x 2mm = 870g<br>7mm x 3mm = 1360g</p>
