Chevy Bolt Roof Rack Foot Pack

prusaprinters

<p>The 3-piece foot pack utilizes the threaded holes on 2017-2022 Chevy Bolt Premier EV (and EUV) roof rails.</p><p>I didn't like the generic clamp style attachment that came with the <a href="https://www.amazon.com/gp/product/B00GA2HKAU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1">CargoLoc </a>cross bars, so I modeled and replaced them with these parts.</p><p>I drive on the highway often and designed this for the top section to be installed/removed.</p><p>I noticed ~25% decrease in range when my surf attachment was on. Now I leave the base installed during the weekdays and attach my cross bars for the weekend; haven't noticed any range decrease since.</p><p>&nbsp;</p><p>Required hardware/parts:</p><ul><li><strong>All hardware should be stainless steel</strong></li><li>(8x) <a href="https://www.amazon.com/gp/product/B07F6YVC1N/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1">M6 x 50mm</a> button head screw; 10.5mm head diameter, 3.3mm head height = $11</li><li>(12x) <a href="https://www.amazon.com/gp/product/B07P8K1K8Q/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1">M6 x 35mm</a> button head screw; 10.5mm head diameter, 3.3mm head height = $10</li><li>(20x) <a href="https://www.amazon.com/gp/product/B009OJZSG4/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1">M6 flat washer</a>; 12mm OD, 1.6mm thickness = $9</li><li>(12x) <a href="https://www.amazon.com/gp/product/B07RR25Z94/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;psc=1">M6 x 1.0 square nuts</a>; 10mm wide, 5mm height = $12</li><li>Cross bars; Amazon (<a href="https://www.amazon.com/gp/product/B00GA2HKAU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&amp;th=1">CargoLoc 2-Piece 52" Aluminum</a>) = $64</li><li><strong>Estimated Total Cost = $106</strong></li></ul><p>&nbsp;</p><p>Installation Instructions:</p><ol><li>Use M6x50mm screws and M6 washers to attach base to the roof rail; BASE SHOULD BE FLUSH AGAINST ROOF RAIL. If not, rotate 180 degrees.&nbsp;</li><li>Place square nuts in the angled openings of the base; two per base.</li><li>Install anchor piece into cross bar by removing one of the plastic end pieces. Place a square nut in the anchor piece before sliding into the crossbar and placing end piece back on. Two anchors per cross bar.</li><li>Use M6x35mm screws and M6 washers to screw top piece into anchor; flat edges facing inward (towards center of car), fillet edges facing outward.</li><li>Adjust distance of top pieces; start with 37-inches and 36-inches apart, outer edge to outer edge. I think the rear is further apart, but you'll figure it out quickly when you try to attach to base.</li><li>Use M6x35mm screws and M6 washer to attach top-cross bar assembly to the base!</li></ol><p>&nbsp;</p><p>Other Remarks:</p><ul><li><strong>Printed with Carbon Fiber PETG.</strong></li><li><strong>Infill at 40%</strong></li><li>Used with my surfboard without issue; user discretion advised for larger objects</li><li>Share excess hardware with friends</li></ul>
