Tampstand for Rocket Espresso Portafilter (E61 brewhead)

NOTE: Pictures of made item (Red ABS) are old version, please download v6 file for better single/dual spout compatibility!!)
Espresso makes me happy. Tamping a single spout portafilter without a tamp stand makes me sad. Paying a ludicrous $80 or more for a stainless steel and marble-inlaid, buffed-with-virginal-baby-diaper-soft-cotton tampstand with some bozo logo on it makes me angry. Me without espresso with a rich thick crema from the perfect grind and tamp, angry, makes the world a scary place. I need to not be angry.
Hence, the swooshy blended just-strong-enough it flexes a little to let me know when I'm tamping just right, ABS tampstand. In red, because Rockets have red glare. :)
5/11/2014: Updated with a v6 file with less faceting. My original finally got overstressed and cracked, so rather than just reprint I did some redesign. The new version fits both the single and dual spout portafilters and provides a bit more strength. Since I needed an 'undercut' for the dual spout, the new file has integral support parts that are part of the print. I prefer to design these in rather than let my slicer provide them since I can better control contact points and removability without excessively marring the desired finished part.
Should fit the portafilter for most Rocket Espresso machines (e.g. the Giotto, Cellini, R58, I think all use the same portafilter handle and basket sizes). Update: The v5 file doesn't support the dual spout, although you can turn the stand around and just use it to hold up the handle end. The new v6 file upload fits both single and dual spout portafilters. It might also fit other brands that are based on the E61 brewhead, but I make no promises.
If anyone wants the original design files to play around a bit more, please let me know; this was drawn in Creo Elements before the export to STL. For example if you wanted a bit more radius blending where the horizontal tie bar connects to the arc section supporting the basket, to increase the strength a bit. Then again, you can also vary the strength quite a bit with infill parameters.
