Magnetic Keychain Coupler with Screw Lock
prusaprinters
<p>This is a magnetic keychain coupler inspired by the <a href="https://niteize.com/slidelock-360-magnetic-locking-dual-carabiner">Nite Ize SlideLock 360</a> carabiner. There are two halves that mate using 6x3mm disk magnets. One half has a captive threaded collar that screws onto the other half to keep them securely together. Each half has a slot for a ziptie - just thread it through and attach a clip, ring, or carabiner.</p><p>I've included 3 versions of each piece with slightly different magnet hole diameters. I usually use the 0.2mm versions for rigid plastic like PLA or PETG, though it may be difficult to press the magnets in on the piece where the holes print upside down. The 0.3mm version should help if you can't get them to fit. This print actually works pretty well with flexible filament (the photos on this page are 95A TPU), and for that I use the 0.05mm versions.</p>
