This is a hanging planter that attaches to metal overhead cabinets in offices. I used a 38mm ceramic magnet that comes in an Edmunds Scientific Magnet grab bag. You can get the same grab bag here (no guarantee that the exact same magnet will be in the grab bag)
I've included the 123D Design file so you can customize the mount to fit a different magnet.
This print does not require supports.
14 hour print using standard settings on a 5th gen Makerbot.
Use super glue to attach the magnet to the mounting plate.
Use super glue to attach the chain to the mounting plate and the planter.
Use a big enough magnet to hold up the planter after watering.
The magnet is not strong enough to hold the planter up on vertical surfaces, like a refrigerator. It should be attached to a horizontal surface, like an office overhead cabinet.
