Adjustable cooler mount

got sick of having bolts fall back through the board when changing cpus so i made this. The fastening knobs may not suite all boards due to collisions with the VRM cooler. threaded rod and nuts are M4 with a thread pitch of 0.7mm. Springs are 30mm x 8mm with a wire tickness of 1mm. washers are 11mm x 1mm with a center hole of 5mm. As always the oriiginal files are included so you can alter them to your needs as they are set for my printers tune. these models where created in 123d design.
