Puzzle 34: 20 parts?

[Jed]

I think this works? I won’t be able to try it on the physical device ’til tomorrow, but it seems to work in the simulator.

It’s no fewer parts than the one that rmsgrey posted, but it doesn’t send an extra red ball through the system.

(This is my first try at posting an image and a jstumble URL, so apologies if I get something wrong.)

Oops! In this attempted solution, I moved the interceptor, but I shouldn’t have done that, because it was part of the problem statement. My mistake; this board doesn’t solve the challenge as stated.

Here’s a corrected version with the interceptor in the right place, but it takes 22 parts instead of only 20.
