Print Settings:

- Material: Tested with PLA and PLA+/PLA Pro.

- Overall print size: 40.39mm tall, 11.18mm diameter.

- Layer Height/Quality: 0.16mm or less recommended, 0.12mm works best.

- Infill: 20% is fine for display, 60% 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.
