I Remixed the Original to get a more classical Style.
-add a Barrel with a bigger Grain
-remove the Original Grain
-add a Grip and extra Printable Screw Heads
-make the Cylinder Pin Longer and thicker for a better fit and hold
-add a changed Version Oskar1990's Ammo to fit in the Cylinder and for better Printing
I create a Full and splitted Version of the Ammo and the Top part of the Gun
Black and Red
Use the "Pin" for the Body and Top part. it should be snug fit.
Assemble the Top part and the Cylinder with the "Cylinder Pin" you can add a drop of super glue in the little hole in the Cylinder to fix the Cylinder Pin.
Use Glue for the Grips, Screw Heads and splitted Parts
I use a cork with a Bottom diameter from 40mm, Top diameter 44mm and 27mm high
As Glue i used Revell Contacta Professional (https://amzn.to/2jNsGjB) this works perfect with PLA and ABS for me
For the used and weathered Look and also for the details, i paint all my stuff with "Citadel" colors from Games Workshop.
