Topeak QuickTrack MTX rack wedge mounted to milk crate with zipties (openscad)

<p>Modified the sled openscad file from <a href="https://www.thingiverse.com/thing:2007835">jridley's design</a> so that instead of using nuts and bolts, I could drill out holes for zipties (sort of like this approach <a href="https://www.youtube.com/watch?v=MvBx_74FzUk">https://www.youtube.com/watch?v=MvBx_74FzUk</a>).</p><p>I haven't looked at jridley's clip design yet. This remix is just for the wedge so that I could mount a milk crate on my topeak rack and secure it with a bungie cord.</p><p>I printed a small version first to get the dimensions of the wedge right for my rack. This will probably vary for everyones 3D printer (in terms of calibration) &amp; also the racks will probably vary slightly.</p><p>I printed in PLA, 0.28mm layer height, with 30% infill. I used zipties across the designed slats, and then I drilled holes with a 3/16" bit so that I could also mount zipties going in the other direction to prevent forward/back movement.</p><p>The print took a while, and one of the edges peeled off the corner of the bed. This means that I can't slide the rack all the way in because the backside is a little messed up. Be sure to print with glue, or keep your bed heated throughout the print to avoid warping.</p><p>Category: Sport &amp; Outdoors</p><p>--</p><p>Please excuse poor code / variable naming. Didn't want to spend more time on this but figured someone might still find it useful in this condition.</p>
