I have successfully assembled the legs right up to the time of 5:40 in the video where I am instructed to install a spring to each joint on the legs. I hold the yellow/black limb with the yellow side up and try to insert a spring. I have tried over 10 times. I have tried inserting the spring on the black end, too. I have tried different pieces. There just is not enough space to get the compressed spring to fit. It's as if my springs have one too many coils.
The ID of my springs is 5.55 mm and the OD is 6.94 mm. The overall free length is 12.15 mm. My springs are made of wire with a diameter of 0.79 mm and have 7 coils. When compressed fully, this gives a length of 5.53 mm. The opening from the top of the button to the bottom of the white gizmo is 3.44 mm; if I add the distance from the bottom of the white gizmo to the top of the shoulder to the top of the button is measure 5.06 mm. In the video it looks like the springs have 7 coils; so I don't know what's changed to create my issue.
Can someone recommend how I can make these springs fit or how I can obtain springs that do fit.
