I needed a storage solution for my HOTO electric mini screw driver and it's bits, so I resorted to the Gridfinity system. Because I wanted to also organise my Alex Drawer to be actually functional and not a messy battlefield.
The fit for the bits is not overly snug, but just perfect so you can remove the bits without lifting the entire holder out of the grid.
Printed this with 1% infill Gyroid no problem and 0.2mm layer height.
