Darth Tamper

I see that you have dark roasted espresso beans. Complete your dark side coffee experience with this Darth Vader espresso tamper.

So far I've rendered a 53mm and 58mm version. If you need other sizes download the DarthTamper-v1.1.scad and DarthVaderReduced.stl to a directory. Open the .scad in openScad, modify tamper_diameter = 53 to the diameter that you need, render, export .stl and print.

DarthVaderReduced.stl come from http://www.thingiverse.com/thing:682497
