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

#9

Here is my design, which I have been using for half a year.

The technical data:

  • Attached with 3 screws of the front panel
  • lasered from 0.5mm stainless steel sheet, the prototype was milled out of 1mm aluminium sheet.
  • 10 degree angle of inclination

Pictures, CAD files and production instructions can be found here (in German):

In brushed and polished stainless steel, the sheet metal would look even better.

Many greetings
Ole

PS. Maybe the winner of the competition could also get a professionally produced bean deflector? I think one or two of them may already have a tamper.:wink:

However, the simplest, cheapest, fastest, most technologically advanced and innovative solution is this one:

An A4-sheet paper with 160g/m² divided in the middle.

The design can be adapted to the colour of your choice.

I have my bullet just a couple of months. I have cut out 2 quarters of a circle in firm plastic. Very cheap, easy to create, washable…And last but not least, it works fine.

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

#14

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

#15

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!

#16

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

#17

I am waiting with bated breath!

#18

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.

#19

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!

Jonas

Awesome! Thank you so much!

#21

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.

#22

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.

#23

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

#24

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.

#25

I used www.sendcutsend.com easy upload, instant pricing and fast turnaround…

#26

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.

#27

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…

#28

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