Pit Droid Build

This Pit Droid uses the Droid Vocalizer Classic for authentic sounds. This was my first droid build and I had a great time with it. I suggest that everyone starts with a pit droid as their first build.

Printing and Finishing

The entire droid was printed in PETG. PETG provided better durability and heat resistance than PLA.

Surface finishing followed a multi-stage process:

• Acetone wipe-down to soften print lines and improve filler adhesion
• Bondo 907 glazing putty for seam filling and print defect correction
• UPOL filler primer for high-build surface preparation
• Progressive sanding through 220, 600, and 800 grit

The goal was not a perfectly smooth “automotive” finish, but rather a screen-inspired industrial appearance that retained subtle texture while eliminating visible print artifacts.

Paint Scheme

I took some liberty with the Pit Droid paint. There is no real official paint scheme. If you build one, have fun with it!

Main Body

• Rust-Oleum Gloss Almond - 334023

Accent Red

• Rust-Oleum Colonial Red - 7715830

Metallic Components

• Rust-Oleum Bright Coat Aluminum - 7715830

Applied to exposed mechanical surfaces, joints, and wear areas.

Weathering and Highlight Areas

• FolkArt Acrylic Paint - Pure Black
• Vallejo Liquid Model Color Mask

I applied the liquid mast over the chrome paint in the areas I wanted to show up as scratches. I painted over the top, then rubbed the mask off. After that I applied a paint/water was over the pieces, focuing on areas dirt would collect. I let it sit for a few minutes then wiped it off.

Electronics

Vocalizer

• Pit Droid Droid Vocalizer Classic

Power System

Inside the head, I used a battery pack to power the vocalizer. There is a lot of room for the vocalizer module and running IR sensor into the eye cavity

Lessons Learned

This ws my first droid. I learned it takes a lot longer that you expect, but its worth the time investment. Enjoy the ride.

Final Thoughts

I’m super happy with how this build came out
