End connectors for the fully parametric drag chain

prusaprinters

<p>This is an upgrade of the <a href="https://www.prusaprinters.org/prints/40345-fully-parametric-drag-chain">Fully Parametric Drag Chain</a> adding an ability to generate end-connectors.</p><p>End-connectors can be attached to the drag chain on one side and offer a customizable set of attachment holes on the other. They can be straight or angled, with an option that straight connectors can be without a wall on either side.&nbsp;</p><p>Configuration options are grouped in the <strong>[Connector]</strong> block. Following options can be configured:</p><p><strong>normal_link</strong>: <i>True </i>- generate normal drag chain link. <i>False </i>- generate a connector.</p><p><strong>start_connector</strong>: <i>True </i>- make start connector link. <i>False </i>- make end connector link. Only works if <strong>normal_link</strong>=<i>False</i>.</p><p><strong>angled_connector</strong>: <i>True </i>- make right-angle connector. <i>False </i>- make straight connector. Only works if <strong>normal_link</strong>=<i>False</i>.</p><p><strong>open_left</strong>: If <i>True</i>, straight connector is open on the left / angled connector turns to the left.</p><p><strong>open_right</strong>: If <i>True</i>, straight connector is open on the right / angled connector turns to the right.</p><p><strong>connector_length</strong>: Length of the connector part (mm).</p><p><strong>num_holes</strong>: Number of connector holes.</p><p><strong>hole_spacing</strong>: Distance between two connector holes (mm).</p><p><strong>hole_diameter</strong>: Diameter of a connector hole (mm).</p><p><strong>hole_end</strong>: Distance of the first hole from the end of the connector (mm).</p><p><strong>screw_head_diameter</strong>: Screw head diameter (mm).</p><p><strong>screw_head_hole</strong>: Screw head hole depth (mm).</p><p>&nbsp;</p><p>For straight connectors both <strong>open_left </strong>and <strong>open_right</strong> can be <i>True </i>or <i>False</i>. For angled connectors exactly one of them must be True.</p><p>&nbsp;</p><p>Attached STL files serve only as an illustration of the capabilities.</p>
