Triangle Key Lock

prusaprinters

<p>A simple key latch mechanism. The key is a triangle shape. Only that shape will fit into the lock and unlock the mechanism.<br/> This is not a perfect lock, as locks only keep out honest people.</p> <p>Ver 2<br/> Updated the Key, Triangle was too big when printed.</p> <h3>Print instructions</h3><h3>Category: Hobby Print Settings</h3> <p><strong>Printer Brand:</strong> Prusa</p> <p><strong>Printer:</strong> <a href="http://amzn.to/2rqZ6Uo">i3 MK3</a></p> <p><strong>Rafts:</strong> Doesn't Matter</p> <p><strong>Supports:</strong> Yes</p> <p><strong>Resolution:</strong> .15 to .2mm</p> <p><strong>Infill:</strong> 15-20%</p> <p><strong>Notes:</strong></p> <p>I used Fill pattern of Grid. Rectilinear might give it a bit more strength in the key.<br/> Might want to consider using 3 Perimeters for the key to make it stronger; found using 2 caused the tube part to snap when people played with the key.</p> <p>Only need supports on the Latch part.</p> <p>When printing the key, print it on the triangle end, or print it on it's side with supports. You might want to use a brim for better support while printing. MK3 did fine without a brim.</p>
