Eureka Libra Blind Shaker

As I like to swap between a bottomless and a standard portafilter, they tend to have different dimensions resulting in the infamous “FH” error frequent with the Eureka Libra coffee grinder. Therefore, I figured a blind shaker would be awesome to have available that would suit. 

So here is my attempt at solving a pretty niche issue. I would recommend clear PETG as there is minimal risk of any unwanted flavours transferring to your grind. Just be sure you dry wipe the shaker down frequently to ensure there isnt any nasty build up occuring. Once I nail the design, I think I'll pay to have a aluminium version machined for the sake of longevity :)

I used 8x2mm magnets to attach onto the portafilter, but this isn't necessary so I have included a magnetless version.

I have had one of these made out of aluminum through PCB Way with great success! Definitely recommend it over the printed version, it can certainly be quite pricey (Approx. $230 USD) but it has held up after almost 6 months of nonstop use multiple times a day with no sign of slowing down! 

If you would like to try one out in aluminum from PCB Way yourself, you can use these links for each part. Just ensure you include "Bead Blast and Anodize" in the Anodize section of the Surface Finish drop down box. Select a color to suit your taste ;)
