3D printed bean deflector

Bullet R1 Hacks
24

Another update. For easier order processing, I have now set up a store for my coffee roasting on Square and made a category their for my 3D printed accessories. You can find the bean chute there and I have a couple other items that will be popping up soon.

Bite the Bullet Coffee - clever!

My deflector is due to be delivered, today!

What else is in the works? I’ve been eyeing that deflector but if there’s other accessories you’re making I may wait and do one order for several items.

27

I don’t suppose you’ll be making the print files available for this? Totally understandable if not.

I am doing the Aillio exhaust adapters and I have a funnel that is used with manual burr coffee grinder by Javapresse. The funnel is used for filling the grinder from a bag of coffee to prevent spilling the beans. I am open to suggestions for other items. I am trying to think of a good way to prop open the door on the bullet when you drop the beans.

I might share it eventually.

I got my bean deflector today and it works great. I did have to run a drill bit through the holes by hand to get the screws through and use the original screws instead of the thumb screws I was using but I’m so glad to get rid of the aluminum foil pan fins that I was using.

Thanks!

Got (and installed) my deflector, yesterday I decided that the slightly small screw holes weren’t a bug but a feature!. It was easy enough to thread the screws through, and, now, when I have to do a deep clean, those screws are held captive in the deflector and I don’t have to fumble the deflector and the screws together when reassembling.

I intended originally for the screw holes to be free fitting, but when I test fit the first piece, I liked that it held the screws for me so I left it that way. Thank you for the feedback!

I didn’t have much issues and liked that I can put the screws into the deflector first. Doing my 5.5kg back to back and will report back of there are any issues with heat.

It is really cool seeing it mounted on someones elses machine.

35

@shane1 it worked wonderfully well. Back-to-back 5 kg at 572F PH and 1lb at 410F PH later all dropping around 430F bean temp for the 1kg batches, I didn’t see any warping at all. It really looked like OEM part! :+1:t4: :pray:t4: :slight_smile:

Does using the tryer not work for you?

37

Sounds good! I might make my own anyway.

You haven’t seen @billc 's hack then for the door handle :slight_smile: It’s a thing of beauty (I still haven’t gotten around to making one yet) - link here

Saw it. Just haven’t personally found a need for it.

40

I just hold it open. I don’t really see it as inconvenience to hold the door open for 10 seconds, but it might be a fun project to try and make something.

I did see that, but thought about doing something a little different… mainly just because I thought it would be fun to design and make on my 3D printer.

How is this working for everyone when FULLY opening the door? I have the printed one here…

BUT I still get beans flying out sometimes. Curious if this would contain them.

@carsononline if you’re asking about the one @shane1 designed which I test ran this weekend with 5kg roasts. When I drop the bean I open the door fully and prop it up with the tryer. It worked wonderfully well! I didn’t get flying beans all over the place. Hope that helps!
