Thomas The Thermonuclear Bomb
Print Profile(1)

Bill of Materials
Description
A crossover nobody expected.
This model is a humorous crossover between the classic friendly blue train universe and the infamous “Little Boy” bomb design — creating something both cursed and oddly fascinating at the same time.
The project is split into multiple parts for easier printing, painting, and assembly.
Model parts:
- Bomb tail fin
- Connector piece
- Main bomb body / warhead
- Thomas-style face assembly:
- Gray face base
- White eye elements
- Black eye details
Finished size:
Approx. 5 × 5 × 20 cm after assembly.
Printing information:
- Recommended layer height: 0.2 mm
- Material: PLA recommended (print profile prepared for PLA, but feel free to use any material you prefer)
- Supports: Minimal supports required only around the tail section
Color recommendation:
For the best final result, pay attention to your filament color choices. Using a darker Thomas-style blue will give a more authentic look — my original blue ended up being a bit too bright 😅
Assembly:
After printing, glue all parts together.
For best results, gel super glue is recommended.
A completely unnecessary crossover between childhood nostalgia and questionable historical engineering 😅
If you print one, feel free to share your make — I’d love to see your versions and color choices!
