Rear Crossmember for Gspeed V3 Chassis

prusaprinters

<p>This is for the r/c rock crawlers…I'm sharing the rear crossmember I use on my Gspeed V3 chassis builds. &nbsp;It will space the rails 2.75" (69.85mm) apart. &nbsp;Designed to use 3mm screws to bolt to the rails. &nbsp;Mount with the flat area up so that the recessed bottom gives clearance for your rear upper links if needed.</p><p>The vertical hole in the center is designed to thread a 4mm screw. &nbsp;I typically use a 4mm grub screw as a body post on bodies with drop beds (see pic). &nbsp;It could also be used to bolt a different body post on for other setups.</p><p>PLA+ or tough PLA seems to work well, though regular PLA works if you're not bashing hard with the truck. &nbsp;I use 5 or 6 perimeters, 5 or 6 top/bottom layers, and a fairly dense infill.</p><p>This crossmember will also work on the Gspeed V1C1 chassis rails, though it's not ideal (I do use it on mine). &nbsp;Due to the shock towers bolting on you'll likely end up using one end hole and one middle hole on each side.</p>
