This is a parametric 1X1 Multibin lid to hold needle files. The parametric values are:

• Number of files
• Handle diameter
• Multibin height (0.5 or 1 recommended)

I recommend choosing your bin height based on the length of the file handles. The bosses adjust to the bin height to prevent the files from toppling over. My assumption is that most needle files will not require a bin height over “1H” (in Multibin speak).
