Gridfinity 2x5x3u

This size is not A1 Mini compatible. There is a short version in the STL files that is 2x4x3u, but that version WILL NOT FIT standard pencils. It will fit pens, mechanical pencils, and markers, but not standard pencils.

I've included a parameteric FreeCAD file if you want to customize it.

I've included magnet holes, but there's a STEP file that doesn't include magnet holes if you prefer that.

This model uses default print settings, but adaptive layer height is used to smooth the slope of the tray.
