This week's design is a Welrod silenced pistol from WWII. I created this for my dad because we used to play Medal of Honor Rising Sun together when I was younger. So I thought this would be a fun gift.

I created this model in Fusion 360 by importing an image and tracing it with sketches. I extruded the handle and most of the details, while I used the rotate tool to create the barrel.

Then I printed it out on my Robo 3D R1 using Hatchbox white PLA. Print settings are listed below. It printed in 3 easy to print sections. The whole thing took about 5 hours to print.

Post Processing:
Step 1: Sand/File any rough spots.
Step 2: Glue the 3 pieces together. No keys this time, but it's pretty clear what pieces attach to what and in what orientation.
Step 3: We applied some Contour Putty to help fill in the seams between parts. Spread it out evenly and sand it down if necessary.
Step 4: We applied some XTC-3D epoxy to improve the surface finish and hide some of the print lines.
Step 5: Apply plastic primer. Give it a few coats, letting it dry completely in between.
Step 6: Apply Hammered Metal spray paint.
Step 7: Apply black spray paint.
Step 8: Scuff the finish strategically with sand paper and a metal pick for scratching it. This gives a nice weathered effect. Leave the handle alone to give it a distinct appearance.
