This is a storage tray for the Kobalt deburring tool from Lowes but others may fit. It a 5x1x3 tray for the Gridfinity system by Zac Freedman.
I printed it in PLA with the default Prusaslicer 0.20mm Quality settings. There was a color change at the first layer about the bit to give the tool shadow.
The author remixed this model.
