Nerf Rival Kronos front plate remixes

This is a remix of the Kronos front plate by CyanAce. The main difference is that this one has a protrusion to allow more room for a follower where you would be using a sixth ball. Specifically the follower is https://www.thingiverse.com/thing:2950444

Basically by having the section hollow like this, you squish the sixth ball less.

You should use the "Rear Portion" from the original thing.
