I made a set of hive hooks for a friend of mine. They are used when doing a hive inspection. They hang off the front of the hive and act as hangers for up to 2 frames so you don't have to set them on the ground.
If you end up printing and using these, please post a photo of your make.
I'm a perfectionist who likes making custom things, and building a reprap printer scratches those itches perfectly. There's nothing more satisfying than designing a part to fix a specific problem and pulling off the perfect print to do it.
