Acaia Lunar Stand for Decent - v2

Designed for use with the Acaia Lunar scale and the Decent Espresso machine.

If your espresso is anything like mine, you'll tend to end up with a fair amount falling outside of the cup, usually all over your lovely scales. This will handily move the scales underneath the drip tray, and ensure they stay nice and clean.

C-Shaped Design: Allows the cup to remain in solid contact with the scales and completely avoids the drip tray, with minimal weighing accuracy effects from any flex or wobble.

Grooved Platform: Designated groove for the scale's silicone mat, preventing any unwanted movement of the cup.

Recommendations:

Additional Prints: Print a shorter version of this riser (I cut it in half in the slicer), to keep your scales off the counter and fine-tune for optimal scale height.

Stability Enhancements: Attach some little silicone or rubber feet to the bottom of the stand, this should stop it from sliding around on the scales. Ensure they're as short as possible, otherwise they can cause it to tip.

Durability Note: As with all coffee-related prints - unless you dip it in epoxy - some coffee will get in between the layer lines eventually. So far though, even with a few espressos a day for a couple of months, mine still looks great and wipes fairly clean. 

Printing Notes:

Orientation: Either side of C, it would be fairly impossible/painful to cleanly print it any other way

Material: PLA+ is recommended, matte or silk is likely not rigid enough - though do feel free to report back any experimental outcomes! PETG/ABS/etc. had not been tested.

Layer Height: 0.20mm height should be doable on the hexagons, however I went for variable layer height in OrcaSlicer.

Wall Count: 3-4 walls are recommended given the need for rigidity

Infill: Cubic (25-35%), gyroid (15-25%), or cross-hatch (15%) should be suitable, whichever is your preference.

Bridge Settings: Thick Bridges were used on my pictured print, though I would have liked to try it without - given the visible layer line it causes. Feel free to try it without if you're confident of your bridging settings.

Updated Aug 2024: 

• Stability enhancements, the top is now thinner, meaning the CoG is much lower and thus it's far less likely to tip or wobble.
• Pattern refresh, the hexagons were a good aesthetic, but hard to clean and time consuming to print. The wavy pattern also allows for more infill (and thus mass) to be placed on the outer side of the ‘C’, which makes it far more stable and rigid.
• Simplified inner geometry, the approach of making inner ribs to give structure but save on filament/weight gave it a look that I wasn't too happy with, so this is simplified now and looks a lot cleaner.
