This was the moment she realized this was the day. Thank you for making it such a special day for everyone, especially my son and future daughter in law.

Thank you for making my son's surprise so much more than he ever expected. I know I posted most of the stuff on thingaverse but I thought I'd post the photo here.

I have printed this out multiple times following you guide lines. It is nearly impossible to get the two pieces to slide together. Specially how smoothly you show it.You have to brute force them together and forget about taking them apart. It prints out great, would really love it if the pieces would like together as easy as you show it. I am using ender 3 pro and also printed on snapmaker a350 same issue. Not usable at this point for me. Great job on the design, wish it worked.

I printed 4 pieces on my Prusa MINI+, and they all are usable with only about 15-20 minutes of work and sanding to remove leftover parts from the supports and other imperfections.

That's normal. You are using an FDM printer. Two things sliding perfectly together require perfect precision, which you get from a resin printer. With an FDM printer you'll have to sand it out for hours to get it right.
