Summary

This fits into the HDD bay in a Sun IPX. I assume it might work in other "lunchbox" form factors (ex: LX, Classic) as well assuming they didn't deviate from the mechanical design on them.

I printed this with PLA, nothing fancy. There's no physical stress on it so it doesn't need much strength.

Like with all these things - I recommend getting one of the multi packs of 3mm nylon standoffs/screws/washers from Amazon.
