stage platform clamp-connector

prusaprinters

<p>On my local church we have some different stage platforms (i.e. Stageworx UniStage) that we want to securely connect. The stage platforms provide for a fastening system (by inserting plastic elements between the profile), but in this case we needed fastening on the underside.</p> <p>I constructed a 3D-printed clamp that uses a M10 screw for applying the forces. The different stage platforms have different profiles. So the left and right side had to match the specific platform-profile. I added a blender-file where you can adjust the platform-profile to your own needs.</p> <p>From you local hardware store you will need:</p> <ul> <li>1x M10 screw (10x140 mm)</li> <li>1x M10 hexagon nut</li> <li>2x M10 ring washer (max. 30mm outer diameter)</li> </ul> <p><strong>Details about the construction:</strong></p> <ul> <li>The screw will take the force in tensile direction. The ring washer increases the force distribution to the 3D-printed part.</li> <li>I added a couple of internal shafts to increase the contact surface in the direction of pressure.</li> </ul><p><strong>Security/legal note</strong><br/> This is a homemade system - use at your own risk. Try and test before use in production.</p> <h3>Print instructions</h3><p><strong>Attention</strong>: make sure to print the piece <strong>laying on the side</strong>. The tip of the tear-drop-shape in the screw hole should point to the top. In this direction ...</p> <ul> <li>... the print layers will take the maximum forces of the stage platform</li> <li>... you need no support</li> </ul><p><strong>Print settings</strong><br/> I printed mine with 0.6mm nozzle and 0,35 mm layer height - other nozzle sizes and layer heights should be fine to.</p> <ul> <li>No support needed (see notes above).</li> <li>25% infill</li> <li>PETG is recommended</li> </ul><p><strong>After printing</strong></p> <ul> <li>add one of the ring-washers inside the slot</li> <li><strong>use a hair dryer to heat the 3D-print</strong> and the nuts and press them into the hexagonal holes of the print with sufficient force. (otherwise the nuts will not fit inside the holes!)</li> </ul>
