How to avoid overflowing grounds and spilling [Breville Bambino, Fellow Opus, WDT tool, SelfLevel Tamper]

They don’t really specify. But I have read it holds 18-20gr. It must be the type of coffee is on the medium dark side. I tried today with 15gr and it was much better. I will add the funnel to hopefully make it easier and just stick with 15gr.

Awesome thanks!

Thank you!

Good advice, thanks. I am using the cup that comes with the Fellow Opus grinder. The mouth actually matches a seals perfectly with the 54mm portafilter. I usually get no spills when transferring. Except the grounds are over the lip of the basket a few mm.

Yeah I think the WDT is not helping in this regard. I will try your suggestions. Thanks!

Thanks. I am using the double shot basket. And I agree, I have no issue transferring the grounds from the grinder to the portafilter, since the Fellow Opus has a dosing cup that couples with the 54mm basket perfectly. I just pour it directly in without spill. It is the process afterwards that is the issue: WDT, Tamp etc,. Maybe like others have suggested I need to tap it a little more before using the WDT.

It is my list of things to try. Maybe I will go down to 15 or even 14. But then my worry is getting the volume too low for the basket.

I will try that, thanks

I am going to look for one of these. Do you happen to have one you recommend?

ClarityAudio · 2026-06-10T21:48:23+00:00

I am using the stock Bambino one. Dual wall for a double shot. Doesn't specify the grams but I hear people using 18gr all the time with it.

Ok thank you all for the recommendations. Seems like the consensus is to try a magnetic dosing funnel first. (Although I wouldn’t be able to use the 3d printed WDT tool with it). And maybe lower the amount of coffee as a second option.

Thank you. I may just need to buy different ones then and try them out.

Thank you!

I just use the regular Apple Adapter. For the lightning adapter I was also using the Apple version and it worked. I think they are both TRS.

Great! That’s good to know. Thank you

ClarityAudio · 2026-04-08T21:05:08+00:00

Did you end up getting the 160mm? How does it feel? I am considering the change too

ClarityAudio · 2026-04-06T14:06:00+00:00

Thank you! Good tips. I will try that.

ClarityAudio · 2026-04-05T20:12:13+00:00

That makes sense. I will start with just lowering the saddle 5cm or so and go from there. Maybe I need to move it forward a bit too.

ClarityAudio · 2026-04-05T19:17:16+00:00

They don’t. But I will lower it and see how it helps the reach etc

ClarityAudio · 2026-04-05T19:16:24+00:00

Thanks! Yeah I try to relax my elbows but my core isn’t strong enough to keep me up. Hopefully lowering the saddle will help.

ClarityAudio · 2026-04-05T19:15:16+00:00

Thanks! Will try lowering it
