Combination of grizzie17 and Roboter32's amazing work to make some changes to the Gridfinity Refined and Re-Refined bin bottoms.

You can find the base plate models on Gridfinity Refined

Edit 28/12/2023: The model has been improved by kamtschatka. Fixing some of my mistakes and providing more customization options! Check it out!

Fusion 360 file is parameterized to make up to a 7x7 grid. Adjustable fill as well.

Default magnet holes are for 6mm x 2mm magnets.

Edit 25/12/2023: Turns out the 6x2mm magnets I ordered are actually ~1.7mm thick. If you actually have and are going to use 6x2mm magnets with the current model it might break the bridge. You'd have to adjust the MagnetThickness in the parameters in the f3d file to accommodate the added thickness.
