Corrective Bracket (CoBra) remix for z-brace mod (Sidewinder X1 version)

prusaprinters

<p>This is a remix from the mentioned original CoBra by pseudo6626 to alow it to use it with the Stage I brace mod (<a href="https://www.thingiverse.com/thing:4375609">https://www.thingiverse.com/thing:4375609</a>) by 3DCanh.</p> <p>I have redone the bracket file that pseudo6626 already posted to improve the mesh on the frustum cutout and to correct for a minimal missalignment of the hole for the leadscrews. Also I had Issues with his frustum version because my stock leadscrews could not properly mount to the bearing in the frustums, so I dropped the bearings down a little.</p> <p>The installation is straight foreward and you can use the stock bolts. If you want to build the z-brace completely new you need the bottom brackets for Stage I from the thing-post by 3DCanh as linked above.</p> <p>Have fun!</p> <p>UPDATE --- 2021-01-28 ---</p> <p>Added a tensioner system to prevent the frustums from wandering upwards on the leadscrews. There are two variants:<br/> 1) Spring loaded type (uses a weak* spring of at least 16mm length and 7 mm inner diameter) - only works for the Stage 1 z-brace remix</p> <p>2) rubber band type (uses two rubberbands per bracket/frustum) - works with the original cobra design aswell as the Stage 1 z-brace remix, BUT you need the remixed frustums!</p> <p>*: the spring should only be very lightly compressed or even better installed with a slight airgap between the end of the spring and the bracket to prevent overconstraining the leadscrew!</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>Artillery Sidewinder X1</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>Yes</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2</p></div><strong>Infill:</strong></p> <p>20%</p> <p><strong>Filament:</strong> Tecbears PETG Grey</p> </p></p> Category: 3D Printer Parts
