Master Lock 175 178 Combination Reset Key

prusaprinters

<p>Needed to reset the combination on a master 178 after decoding it and I didn't have the tool. I took measurements of the keyhole and did some guessing based on photos I found online and made this small key that works just like the original.</p> <p>I included one with a 4mm hole if you want to put it on a keychain, though I have not printed this version.</p> <p>To use:</p> <ol> <li>Unlock or decode the lock</li> <li>Slide in the tool and press it into the back of the hole on the bottom side of the lock, you will feel spring pressure pushing back.</li> <li>Rotate the tool 90 degrees either left or right to lock it in place while pressing the tool inward.</li> <li>Dial in the desired combination. (If the tool is inserted and seated correctly, the wheels should spin freely with no detents, or at least a lot more freely than normally dialing the combination)</li> <li>Remove the tool by rotating 90 degrees in the opposite direction and sliding it out.</li> <li>Combination should be set now, remember that the lock will not lock itself while the combination is dialed in.</li> </ol> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>No</p></div> <p><strong>Resolution:</strong></p> <p>.24</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>100</p></div> <p><strong>Filament:</strong> Hatchbox PLA Black</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>200 C Nozzle<br/> 60 C Bed <p>Printed on an Ender 3 v2</p> </p></div></p></p></p> Category: Tools
