Fixed the following issues from the orignal design

1. you need 8 pins and not 6 which desinger did not include on build plate or in notes (use BRIM only)
2. you need to print on 4 different plates as shown on my images as the sizes are wrong
3. springs the 4 of them 2 of them dont even touch the plate so you do need support and must be printed at 90% to fit
4. when connected all the 8 pins they dont fit correctly so to make it work i used torch to touch both the car and the pins to melt a bit then fited.

5. Added Outer Brim Only so it does not fail on prints.
