This is a simple rack that holds 50 brass casings for cartridges designed for .270 Winchester. It should also hold similar casings for bullets around a 6.8mm diameter. The main purpose of this part, especially v3, is to hold casings for drainage and drying when they are hand-washed rather than cleaned using a case tumbler. Versions 1 and 2 are simpler versions from earlier in the design process that may still be useful in specific scenarios.

No specific settings should be needed, I printed mine at 0.2mm layer height with no supports needed.

V1 has simple round pegs for holding casings. The pegs are 6.5mm in diameter, so they are loose but will still hold the casings upright.

V2 has pegs with a plus-shaped cross-section, allowing for better water drainage. The pegs are 6.65mm in diameter to hold better while still having space to slip into the case necks easily. This allows them to hold the casings upright more securely.

V3 has a ledge at the bottom of the pegs to allow for airflow and increased drainage. The pegs are the same 6.65mm diameter with a plus-shaped cross-section as V2, and they are elevated to accommodate the height of the ledge (see pic #2).
