AliExpress Stealth Press Kit Part Remix

I purchased this Stealth Press kit during a sale, and when going to print their modified parts found that some of the modifications made either introduced new requirements for supports or did nothing to address existing issues.

I've made minor modifications to resolve these issues.

I found that the kit supplied M3 bolts for these parts only just reach, and given the strength of the keybak replacement used, should probably be replaced with something a little longer for piece of mind.

Improves parts to remove supports.
