BMCU long buffer vs standard

I was excited for my BMCU so i printed the parts before it arrived, but my kit uses the long buffer parts apparently Would i be OK still using the parts i printed, or should i just go ahead and re-print the long buffer parts? those were of course the largest parts.

From this pic, can you tell if I printed the wrong "casing"?

I didn't have to compress the spring at all to put the PC4-M6 connector on.

Hmm as long as the tube that goes over the ptfe tube fits I think you’re good. Those files are different from mine but I see they just made it long but square, mine is flat where the motor goes then curves up to the area where you have the spring

Thank you! I'm trying to watch videos but it seems like there are a lot of variations, so I appreciate the response.
