This open-source sample holder is designed to hold a semiconductor wafer part on a smooth 8mm diameter rod.
This is an improvement on the last version - as now you can change samples easily using tweezers and one hand only. It uses less plastic than v2 and has a cutout for samples that are short.
Print on your favorite open source 3-D printer and enjoy. You can hold it to the smooth rod using m3s and the thumbscrew.
Use the thumb screw from http://www.thingiverse.com/thing:30500
