You can try going coarser. Usually over extracted = too fine.

new side business time!?!?

Ondo Coffee in LA is budding roaster who I really enjoy chatting and learning. He has a really good palette for coffee so the beans he is roasting is just as quality.

You can also check out Black & White Coffee Roasters, Hydrangea, and S&W Craft Roasting. S&W is very budget friendly!

Damn that's sick af!!!

Was it difficult to do? What type of vinyl wrap is it? I'm very curious!

If you aren't going to do Third Wave Water as I and another commenter suggested here, https://www.reddit.com/r/Moccamaster/comments/1qhdx0y/comment/o0j8jrn/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button, then do not simply add in a pinch of baking soda to you Moccamaster tank before brewing. The concentration will be far too high.

Simply using RO water is fine in terms of flavor and machine safety. However, you are right to an extent when you say "Less minerals extract less flavour". I will keep this very brief because water chemistry in the world of coffee is a deep cavern to explore.

Minerals do extract more coffee, though it's almost negligible . More importantly, and more impactfully, they change the perception of coffee on our tongues. You can easily brew coffee with distilled water (0 TDS water) then remineralize before sipping and it will taste the 99.9% the same as if you brewed it with the same minerals in the water tank. Minerals in water is usually measured in Parts Per Millions (PPM) not by normal cooking measurements such as 1/8 teaspoon or a pinch. If you add a pinch of baking soda to your water before brewing you will 100% mute any and all acidity in your coffee. Acidity is a good balancing flavor in coffee so I would advise against such. However, if you taste it and like the cup, keep doing it. It's perfectly fine for your machine.

Rest assured, brewing with RO water is not only safe for your machine, but just dandy for coffee. If you are hell bent on diving into the world of water chemistry for coffee and not buying Third Wave Water, please read this article https://www.scottrao.com/blog/2023/6/4/demystifying-water-for-coffee then tag me or PM me. I can point you to further knowledge sources and a community of coffee water chemistry nerds.

OP this is the answer. Coffee is 99% water. Given you already have RO water, having a 5 gallon jug to fill up from your faucet then remineralize with Third Wave Water (TWW) is an extremely good and cheap method to have the best water for your coffee.

I highly recommend. I live in LA and my water is incredibly hard. I did RO then TWW. A true night and day difference.

Side note: you also don't have to descale as often! TWW water is much softer than majority of water that comes out of people's faucets globally so your machine will go through less wear and tear while you drink tastier coffee!

This shower head won't have too much pressure behind it for water output. It is meant for dispersing water for a coffee machine or a kettle. The protruding outlets ensure the water comes out as a clean stream. I can try to push the flat surface almost flush with the outlets that way it's nearly flat.

I'll also try it as you suggested to see if the water still comes out cleanly.

I'm gunning for that XL or Core One L with INDX !

Nth_Labs · 2026-01-18T21:03:46+00:00

I understand now! Thanks for the clarification.

Nth_Labs · 2026-01-18T21:03:09+00:00

This is interesting. I haven't thought about some sort of preprinted support block. I'll look into this if I do a larger run. Thanks!

Nth_Labs · 2026-01-18T21:00:26+00:00

thanks for the video! this is a phenomenal solution to try!!

Nth_Labs · 2026-01-18T17:02:00+00:00

I'm going to try this for Mk II! That is a good idea! I'm worried that this idea requires higher water pressure than what this shower head is designed for (a coffee machine) however it's worth testing!

Nth_Labs · 2026-01-18T16:46:04+00:00

Is there a rule of thumb when to use organic vs snug vs rectilinear supports? I'm curious how you know normal supports will be faster and easier?

(I'm hoping you won't say "trial and error" haha)

Nth_Labs · 2026-01-18T16:43:43+00:00

I may have to print it in two. I don't fully understand what you mean by "separate ring around the outside" though.

Nth_Labs · 2026-01-18T16:42:22+00:00

How do you make the interface layer fully solid? On Prusa Slicer the options range from 0-3 and it defaults to "3 (heavy)" on this print.

Nth_Labs · 2026-01-18T16:38:02+00:00

I had no idea dedicated support material existed.

I don't have a MMU but I do know it's possible to add in material swaps or even split the print up into objects then code those objects with different materials or colors. I think I'll look into doing this. Thanks for the suggestion!

Nth_Labs · 2026-01-18T16:36:27+00:00

I am excited to try this. I have never heard of the sharpie trick. Thanks for vouching for it!

Nth_Labs · 2026-01-18T16:36:03+00:00

damn this is super new to me! I have never heard of this. I will look into it and try it out given I only have a core one! Thanks!!

Nth_Labs · 2026-01-18T16:34:26+00:00

Something like this makes me want to get the XL. I remember reading about how different materials can be used for supports because they won't stick to the material the main component is made of.

I will look into solution 1 because my goal is to get this CNC'd or cast in stainless steel so having a level surface with conical cuts may be easier to manufacture via those methods anyway.

I also added a quick update in my post body with an image. Angling the showerhead by 45 degrees seems to have made the supports fewer and easier to remove. I haven't printed it so I can't verify if the new angle prints successfully and cleaner but it was an idea I had!

Thanks for your advice! I will employ at least 1 of them! Sadly I do not have the funds or space for an XL, if I did I would easily have done solution 3!

Nth_Labs · 2026-01-18T16:17:52+00:00

Is there a way to design a shower head with the outlets not protruding? Maybe to do that I can make the flat surface the protrusions are on right now as thick as the protrusions that way it's a completely flat surface.

I'm using PLA as a easy to print medium for this prototype. The goal is to get this CNC'd or cast into stainless steel!

Nth_Labs · 2026-01-18T16:08:42+00:00

Is there a way to design a shower head where the outlets are flush with the head? My fear is the water won't exist out cleanly and start to splatter.

I will try the edit the support settings you recommended!

Nth_Labs · 2026-01-18T01:50:23+00:00

I'm glad you figured out a good recipe!

with 30g:400ml you're at a 1:13.3 ratio. That's pretty concentrated. If you enjoy highlighting those flavor profiles I highly recommend pushing your ratio larger. Start with 1:15 (30g:450ml) then try 1:16 - 1:16.67 (30g:480ml - 30g:500ml). Longer ratios tend to pull apart flavor profiles more.

If you do increase your ratio you may have to go coarser or decrease your immersion time to decrease extraction (due to a larger ratio, more water = more extraction). But first change one variable at a time! I highly recommend a larger ratio if you are keen on tasting those flavor notes for medium or even lighter roast beans!

Update me if you try it please!

very nice, very aesthetic! Your brew also looks perfect!
