Official Bullet R1 Bean Deflector / Guard Contest (Deadline 1/16)


Here is my design…Martin Oets


How can it come ur letters are green on the board ?


Only the power, drumspeed, fanspeed cooling speed lights are green. The temp and off/cool lights are red.


Here is my design. I really wanted to cut out and make a working prototype but ran out of time. Anyways, my idea would be to put some rare earth magnets inside the legs so fins can easily pop on and off without any screws and be a little bit adjustable as well. Here is a little video. Let me know what you think!


Thanks everyone for the entries. Jonas and Jacob are out of the country till next week. Will announce a winner soon after. :slight_smile:


I am waiting with bated breath!


Hey all. We’re back in the office after the long Lunar New Year holiday, and this morning Jonas decided on a winner. Or should I say… winners?

Stay tuned.


We have found two joint winners.
Patric and Eric.

Thanks to everyone for submitting your ideas. Sorry it took forever to judge. I had a small biking accident that held me back.

Patric: Very simple solution of mounting a deflector directly on the cooling tray was something I was looking into as well. I do think that they could be a lot smaller. Beauty of this ideas is that it can be lasercut as one flat piece.

Erics idea of using a magnet through the plastic is great as it does not scratch anything on the front of the Bullet.
It would be great if we could make these drawings available to everyone.
I could also help draw them up and make them availble for 3D printing / lasercutting.

An espresso kit is on the way!



Awesome! Thank you so much!


Hi Ole, our tool shop made a laser cut after your design. I must say it is genius and works like a charm! Kudos your way :clap:
Now it seems that almost all Bullet owners in Denmark that I know of would like to have it also.


Hi Lav

Thank you very much! I am very pleased that so many like the bean reflector. :smiley:
With a collective order, it can even be produced very cheaply.
At least here in Germany the laser cutting of 3 bean reflectors costs only a little more than with one.


I would be interested in one here in the U.S. Anyone able to laser cut?


I’d like to modify the step file linked above into an STL for 3d printing.

I have the stl file flat, but I need to figure out how to bend it correctly, working on that now.


I used easy upload, instant pricing and fast turnaround…


That is a great option. I will likely just end up doing that :slight_smile:
The thing I was attempting to do is make it where anyone with a 3d printer can just hit print and be done with it, instead of whipping out their credit card number…

However, the available plastics that 3d printers use may have issues with the bean temps coming out of the chute.


Yes I think most 3D filaments might find the temperature a little deforming after a time. The stainless steel one cost me about $20 and isn’t likely to need replacing…


I wish we had such places in Europe with an easy online service like that…


I sent the step and dxf file to a local sheet metal cutter and they came back with something too small.

Any chance you have this file in a true to size pdf? They said they generally print a pdf and use it as a template for cutting.

I looked at the files and could not see the actual overall sizes for them to use…


You can use the free Autodesk DWG TrueView program ( to print the file to PDF. You may need to install a PDF printer, e.g. . You have to set the scale for printing to 1:1. The holes should then have a diameter of 5.3mm on the paper as indicated.


I have a family member with a few laser machines and printers, including one that can cut magnetic-backed vinyl. Happy to see what she can do with these designs if I am able to get the files.
