Use the OpenSCAD files to customize it for your application, print on your favorite open source 3-D printer and enjoy.
The optics base here comes in two flavors. In the first it is just flat to be used on a normal table. In the second it has a small cylinder cut out in the bottom meant to glue in a magnet - then quasi-permanently hold the position of the component on a magnetic surface.
If you wish to remove or add the hole for the Magnet in the .Scad file, change the line:
magnet_hole = true;
magnet_hole = false;
