First of all, a huge thanks to @Acheituno for this awesome design. Before printing this, I read through the comments and listed carefully to the recommendations that many others had made - separate the barrel from the stock, add a guide peg, and create a latch for locking the pistol closed. I did all of these customizations and made the rod for the the cylinder a fraction smaller as the tolerance was too tight.
I noted that I needed to sand the trigger and finger guard down to fit them, but this took a few seconds so really wasn't a necessary modification. I would also like to mention that you might want to choose to find a 5mm metal rod to use for the cylinder rod if you actually plan on spinning it, as the nature of fdm printing something like this makes it quite easy to snap.
Aside from that, I'm quite happy with the result, and please note that I did omit the rod at the bottom as it is purely cosmetic and prevents the opening and closing of the revolver. A piece of old rope or wire is recommended as this part needs flexibility for functionality.
Please visit Acheituno for a stand and bullets for this design, and I hope this remix is useful to you.
If you like this design, please give it a boost!
