<p>This is an OpenSCAD model for Lowe &amp; Fletcher locker lock keys (flat, blade-like model). Keys for these locks might be hard to come by outside of UK, so I devised this model to be able to duplicate keys.</p><h4>How to use</h4><p>You will need an original key, and measure its cuts. Keys have 1mm wide cuts, with each cut step also being 1mm. In the script, the key profile is indicated as an array of cuts, starting from the tip (which should be maximum cut/5 for 2mm / two steps). The provided example file has been modeled against a ZA type short key, but adding enough zero cuts (0) it is possible to make longer keys as well.&nbsp;</p><p>Do not forget that you will also need to add a small notch at the end of the key as well, to allow it to turn in the lock.</p><p>Tested with Prusa MK3S+ as follows: print with 0.10mm layer height, 100% infill. Should take, depending on the length, around 10 minutes when printed with PLA. <strong>Be aware that plastic keys are not nearly as strong as metal keys </strong>- particularly with longer keys or stiffer locks, you might need some lubrication or the assistance of a metal turning tool<strong>.</strong></p>
