V-Core Bed Spring Bracket
thingiverse
Here's how I've modified the Rat Rig V-Core bed to add springs. These attachments are mounted directly onto the bed frame. The bracket, as such, is probably universal for all or most 2020 extrusions. You can find Fusion 360 links below. Make sure the pin is as long as needed. My springs have an outside diameter of 9.8mm and an inside diameter of approximately 5.5mm. https://a360.co/2w6g4XC https://a360.co/2w6pvpX This setup is only temporary for me, until I get my final aluminum bed. I'm not a fan of four-point mounts, and I prefer the bolts to go through the springs instead of beside them. The mounting design will cause some deflection.
