Based off of some fairly specific math, here is the first iteration of kicker design I’ve come up with so far. It’s roughly 9" tall, and 1/4" thick. It’s 0.25 lbs, though that’s not an issue yet. Two of these will have standoffs in between them and be driven by either surgical tubing or springs, adjustable via the holes at the top. It makes contact with the ball at the bottom. I haven’t created all of the standoff holes yet since I’d like feedback.
I cannot do a FEA on this, so where would you guys/gals estimate its greatest structural weaknesses are? Are there any overall shape improvements that could strengthen it?
