Rachet with t-nut for 30 mm aluminium extrusion profiles

prusaprinters

<p>I wanted to mount some cables to my Prusa MINI's Z alu profile using something reusable - that's how this rachet was born.</p> <p>The "T-nut ratchet for 30 mm alu extrusion profile.stl" contains a pocket for an M3 nut. You can fix it with a 15 mm M3 bolt.</p> <p>I have iterated a simplier version with an M4 hole to use it with a proper T-nut.</p> <p>Link to the design: <a href="https://myhub.autodesk360.com/ue282d3d0/shares/public/SH56a43QTfd62c1cd9685643e0a1951e2bb3">https://myhub.autodesk360.com/ue282d3d0/shares/public/SH56a43QTfd62c1cd9685643e0a1951e2bb3</a></p> <p>Update #20200211 - new features:</p> <ul> <li>t-nut turns only one way</li> <li>ejector hole for the M3 nut</li> <li>countersunk slot for the M3 bolt</li> <li>more room for the hex key / screwdriver</li> <li>extra teeth for tighter lock</li> <li>smaller and 60° teeth for easier operation</li> <li>left side of the rachet will not overhang on the 30x30 profile hence allows easier installation even if something is already installed on the side of the profile</li> <li>extra "fat chicken" edition for even tighter cable lock :)</li> </ul> <p>Installation: <a href="https://youtu.be/bvUciTL83wk">https://youtu.be/bvUciTL83wk</a></p> <p>Blogpost about the design process (sorry folks, Hungarian only): <a href="https://fns.pappito.com/2020/02/11/3d-nyomtatas-a-dagadt-csirke/">https://fns.pappito.com/2020/02/11/3d-nyomtatas-a-dagadt-csirke/</a></p> <h3>Print instructions</h3><p>No support needed.</p>
