If you, like me, have too many TP4056 charger modules, and want to organize them using Gridfinity. I've got the perfect thing for you!
The magnet holes are 6.09mm, so you only need to press them in to the holes. No glue required. I also chose to remove the small inner-holes from the magnet holes to make printing easier.
It fits 30 modules in a 2×1 Gridfinity grid, but I also made a 1×1-sized version that fits 14 modules. I haven't tested the smaller one myself as it is too small for me, but it shouldn't not work.
Note: The Gridfinity Design Reference says that magnets should be 2mm thick. But my magnets are 1.7mm thick, and they pretty much sit flush with the bottom.
