Magnet dice

A 16mm six-sided dice with a hollow spherical area inside is designed to fit a 5-6mm spherical neodymium magnet, which can be purchased online for 15-20 cents each. The magnet is inserted about two-thirds of the way through the print and sealed inside. This unique design allows the dice to function in space, clicking onto any common metal surface, enabling users to roll dice on a fridge, whiteboard, or even the side of their car. The internal sphere ensures that the result is random. Please note that these dice will stick together, making them easy to carry as a single unit but also preventing multiple rolls at once. I have rounded the edges to make it more robust and durable, as well as easier to roll. The dice functions normally on non-magnetic surfaces. Here's a video of one in action on a fridge: http://tat.mithril.com.au/Magn... I designed this for playing games in limited spaces or while traveling. The magnets are strong enough that users can easily toss the dice up onto the underside of a metal surface to roll them. They can also be used as numbered markers on a whiteboard, fridge, or similar surfaces. Using dimples makes it easy to color the dots with a permanent marker (I've used different colors). I'm excited about the idea of someone using these in space, like an astronaut on the ISS playing Traveller RPG (or similar) - just hoping they don't interfere with any equipment up there. It's a pretty simple print. I print it at around 80% infill since the magnets are strong and I don't want the inner shell to break from impact. I use white PLA, printing at 200 degrees on a 60-degree heated bed. I print without supports, brim, or raft. I need to be careful where I place the print on the bed in case there are magnetic elements inside the printer. I don't want the magnets moving during the print. If anyone asks, I can create a full set of d4, d8, d12, and d20 - but they might not work as well due to size constraints and magnet dimensions.
