Topeak QuickClick Saddle Rail Mount

prusaprinters

<p>Relatively permanent mount on the rear saddle rails for Topeak QuickClick compatible saddle bags.</p> <p>I made two versions: one flat (original design), &amp; one round so you can slide the whole mount along the rails to find the ideal position.</p> <p>I also uploaded the bare Base.sldprt in case anyone wants to customize the 2-bolt plate extrusion.</p> <h3>How I Designed This</h3> <p>Critical dimensions:</p> <ul> <li>Width of big end of the slot: 3.32 mm</li> <li>Width of small end of the slot: 1.78 mm</li> <li>Slot depth: 2.90 mm</li> </ul> <p>Scaled these by 115%.</p> <p>Counterbored holes for the M5 bolts, only half the original depth of 4 mm, since thickness is critical here, to prevent the pieces from breaking under the compression by the bolts. Used only to help locate the bolts really, but it also lets standard 1/4" 5 mm hex bits reach it without hitting the rail body first.</p> <p>I decided not to add the locating stub on the original part (almost impossible to see in the image below - it's between the two bolts), since the idea is that you print a bunch of these &amp; leave them on your bike(s). So you can suffer the slightly-more-cumbersome one-time installation. This saves you from printing more supports.</p> <p>I am aware there are at least 2 variants of the mount out there - the flat styled one shown immediately below, &amp; the round styled one in the Compatibility section. I only own the flat styled one, so that's the one I used to model the part in SW. I think they are both called QuickClick. I believe I may have the older version, &amp; that they've been replaced by the round style (see further down).</p> <p>I can't seem to find the flat style on the Topeak website (21 Feb 17) at all.</p> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/47/80/bf/24/3a/BG1718_964274e5-e8b0-410a-806a-8754b7da2acc.jpg"/></p> <p class="detail-caption"><strong>Source style.</strong></p> Assembly &amp; Instructions ======================= <p>The original hardware included:</p> <ul> <li>x2 M5 x 16 mm bolts</li> </ul> <p>You should add:</p> <ul> <li>x2 M5 locknuts (7.92 mm defining inscribed circle)</li> </ul> <p>You may need longer bolts depending on your saddle rail diameter. I would go longer regardless.</p> <p>Print either the FLAT pieces or the ROUND pieces. You'll need the base &amp; the plate. The locknuts set inside the plate. Wide wing tips go up.</p> <h3>Compatibility</h3> <p class="detail-caption"><strong>Your clip (on the bag) should look like this.</strong></p> <p class="detail-image"><img src="https://cdn.thingiverse.com/assets/a8/a6/26/be/be/topeak-drybag-wedge-quickclick-saddlebag-medium-black-EV185432-9999-3.jpg"/></p> <p class="detail-caption"><strong>I am not positive, but I think bags with this style of mount will also work.</strong></p> Future ====== <ul> <li>angled variations; I've had problems especially with my saddles too far forward such that the bags need to make a large bend to fit the angle between the rails &amp; the seatpost</li> </ul> <h3>Updates</h3> <p>24 Feb 17: Just mounted one. Almost everything was perfect the first time. The slot was perfect, but the wall thickness where the clip actually snaps in place was a little too thick. I used a knife to thin it down a little bit. I would also recommend manually pushing the snapping bit (on the bag) up to further secure it even if you hear the click. I printed both pieces so they didn't need any supports. I needed longer-than-16 mm bolts. Exacerbated by the orientation, there was enough warping that one of the hex insets was too big. I wrapped the locknut in electrical tape &amp; wound the bolt through until it was set in the plate. Tightened fairly tight, with no issue.</p> Category: Replacement Parts
