Print the "dryingRack.v5.stl" to get the upside-down case drier with angled spikes.

This is a parameterised case drying rack I've designed in OpenScad, after I could not find a good one here on thingiverse.

Optional rows/columns, pins, spacing, thickness of base, angle of pins, etc.

Default configuration is sized for 308 win cases.

As a bonus it can be configured to hold cases standing on their ends - the file dryingRack.v5-washingInsert.stl is configured this way. (As you can see in the photos, too)

This I use as an insert with a Hornady sonic cleaner; I got fed up with the cases just being in a heap and sometimes air got trapped, etc, the cleaning was never ideal. This helps.

I highly recommend to download OpenScad and use it instead of the thingiverse customiser, it'll be much quicker. OpenScad is very simple to use, it'll shouldn't take 10 minutes to learn the basics. There are plenty of tutorials around, too.

Have fun!
