Cylinder Lock (fully functional, parametric)

prusaprinters

<p>It's a fully functional cylinder lock that offers 5⁴ (=625) different combinations.</p> <p>You will need 4 springs from a ball pen (diameter = 4 mm, Length &gt; 19 mm, tolerance is quite high and parametric) or let gravity do the its job for a first test.</p> <p>To create a custom lock, open the .f3d-file in Fusion 360, go to "change Parameters" and set PIN1STUFE to PIN4STUFE an a value between 1 and 5. It will adjust the pins and the key accordingly.</p> <p>Also see <a href="https://youtu.be/lX2YUn6JloE">https://youtu.be/lX2YUn6JloE</a></p> <h3>Print instructions</h3><h3>Category: Mechanical Toys Summary</h3> <p>It's a fully functional cylinder lock that offers 5⁴ (=625) different combinations.</p> <p>You will need 4 springs from a ball pen (diameter = 4 mm, Length &gt; 19 mm, tolerance is quite high and parametric).</p> <p>To create a custom lock, open the .f3d-file in Fusion 360, go to "change Parameters" and set PIN1STUFE to PIN4STUFE an a value between 1 and 5.
