4WD truggy shocks with 40x3.2mm rod

This is the second version that delivers results. To achieve a great print, rotate as needed. The diameter of the springs needs to be precisely 15mm. The rod fits securely and doesn't slip off easily. I also added a few lines of shallow threads at the end of the rod to enhance the grip. The halves are held together by the spring's constant force. The rod guarantees smooth, linear motion while keeping the construction perfectly straight. v2a features strengthened chamfers at both ends for added durability
