Bench mountable cable clip for optical table with M6 or 1/4-20 screws

I made this cable clip for an optical bench. The bottom is thick to hold it flush to the table, and the top is thinner to offer some flexibility in clipping the cables. 

It mounts to the table with one hex socket head screw. The screw can be either 1/4-20 or M6, which are the standard imperial and metric screw sizes for optical tables.

Supports are not needed. I found that 15% infill gave good results. 

STL and gcode files are provided for a single clip or 9 clips in one go. 

Photos show the clip in jet black PETG and rainbow luminescent PLA.
