Eye bolt socket
thingiverse
If you've ever been frustrated from having to manually twist those eye bolts in xmas tree stands here is a 3/8" drive socket you can print out so you can easily hook it up to a ratchet or, what I prefer, a cordless drill. It even has grooves to snap in so it won't fall out, Let me know if it's too small and I can make adjustments.
