The 4 bore centerfire rifle cartridge was designed by British explorers in the late 1800s.
Print this for props, display, education, training, just because it's cool, or scale it up to become a container.

Print Settings:
- Material: Tested with PLA and PLA+/PLA Pro.
- Overall print size: 119.3mm tall, 31.3mm diameter.
- Layer Height/Quality: 0.16mm or less recommended, 0.12mm works best.
- Infill: 10% is fine for display, 20% or more recommended for snap cap use.
- Print Speed: 50mm/s or less recommended. I do 40mm/s for cartridge, snap cap, and case piece; then 30mm/s for bullet piece. I also do 10mm/s initial layer speed.
- Adhesion: A brim might be needed, depending on the printer and bed type. I have a textured PEI bed, and with proper calibration, additional adhesion isn't needed.
- Post print: The pieces may require some sanding or filing for proper fitment if the bottom layers bulged out a little. Fitment should be a little snug, but easy to take in and out. A properly calibrated setup shouldn't need additional work.
