A different view of the M87 black hole image.

I know posting a picture of the tactile black hole doesn't help its intended audience, but if you're interested in one please get in touch. Print-it-yourself files will come when the design is more final.


Prototype number two: added text for the benefit of sighted folks as well.

I gave a couple of these to the lady who wore the black hole dress at the press conference. She's going to use them as props in a grant presentation, and I hope she'll have some suggestions.

Okay she did suggest making it bigger so you could use it as a cup holder but I hope she'll have some *other* suggestions.

Update on the tactile black hole image:

I have now made available the printable files for prototype number 2:
thingiverse.com/thing:3609205
This will also be the location for future updates.

Details are there, but it should be possible to print the object on most plastic-extrusion 3D printers.

There are a number of other 3D-printable scientific visualizations (and other things) available from that same location.

@aeveltstra
Er, it's a pen, albeit one I got on a tour of the building where Mitsubishi Heavy Industries builds rockets.

@anne Absolutely gorgeous! I'd love to have one for myself. I really hope you'll post print-it-yourself files soon, and I hope my 3D-printer-owning friends will print it for me!

@breakthesystem
Here are the files for a similar object I made, though not blind-accessible:
thingiverse.com/thing:2723399

@anne Oooo. I love this! Yes, I would love to know when you’ve got it complete and I will gleefully print it for some kids I know. They aren’t blind, but I think this would help them nevertheless.

@KARiley40 I'm planning a version 2 with text for sighted people. (Sadly it's hard to combine the two, for technical reasons, though I'll try. No, wait, I think I can totally do that!)

In case I'm disorganized and forget who wanted them, they'll appear on my thingiverse page (which already has some cool science things):

@anne Hehehe!! I will keep an eye out for the finished design!

@anne When I see photos of 3D-printed objects, I sometimes try to rotate them with the mouse before I realize that photos can't do that. 😐

@anne Oooh, when the files are ready, I'll definitely want to print one!

@anne Got it printed up today! It's going into our permanent collection of 3D printed educational objects. Thanks!

@delibrarian
That's fantastic! Please let me know if you get any interesting connects or suggestions!

@anne What exactly does the braille say? I want to make a card to go with the object for our collection.

@delibrarian
It says the same thing as on the bottom of the two-color version:
EHT Collaboration
Combined 2017 data
Black hole in M87
Actual observations

(Incidentally you don't actually need a two-color printer to print the easier two-color version: using Slic3r PE you just add a filament change after the first two layers.)

@anne Great! And thanks!

We may try the filament change the next time we print. This one did come out a little rough because of some problems we're having. But everyone I've showed it to loves it!

@anne
This is so cool! Can I get the 3D files? 😁

@efz1005 The plan is to put them up on my thingiverse page once I've got past the earliest prototype or two:
thingiverse.com/peridot_facete

@anne oh my can I buy this? This is such a forking cool project!

@anne I would put random things in it, seems appropriate

Also SUPER COOL

@anne that is super rad, is the stl available?

@Brian Indeed! There's a thingiverse entry:
thingiverse.com/thing:3609205

It'll be updated as I improve the design or add options.
