Original Post: July 3, 2026

When I moved to Serbia, I was pretty lonely. New country. New language. Not many people around.

One day I noticed that one of my neighbors was blind. He almost never went outside alone. Usually there was someone helping him.

I didn’t have some big plan. I just thought maybe I could ask if he wanted to go for walks sometimes. So I did. We started walking together, and somehow became friends.

For about a year he invited me for lunch almost every Saturday. He cooked. We ate together. We talked. Sometimes I helped clean up a bit. Nothing dramatic, just regular Saturday lunches. I think a big part of my Serbian came from sitting at his table and trying to keep up.

At some point we were talking about geography. Which countries border Serbia. Where the sea is. Where the mountains are. How the region fits together. And I realized something obvious, but it still hit me. For me, if I forget where something is, I just open a map and look again. For him, a map is mostly memory.

He can remember facts, but he can’t just look at the shape of a country, the border, the coastline, the mountains, and rebuild the picture in his head.

His birthday is next week, so I decided to make him a map he could explore with his hands.

This is my first real 3D project, and it became a much bigger than I expected.

I had to take GIS data, country borders, elevation data, capitals, sea areas, tactile labels, Braille cards, and somehow turn all of that into printable STL files.

The annoying part was that “looks good” and “works by touch” are not the same thing at all. Borders can’t be too thin, because then you don’t feel them. They can’t be too thick either, because then everything becomes a mess. Mountains need to be there, but not as a noisy blob. The sea needs a different texture. Countries need numbers, but not every country could have one - some are just too small. One of the biggest headaches was Greece: all those tiny islands add detail visually, but on a tactile map they can quickly turn into noise. A lot of this project was basically trying to find the balance between detail and clarity, so the map stays clean enough to be readable by touch.

The whole map also had to be split into puzzle-like tiles, because I can’t print it as one piece. So I added little interlocking connectors, partly to hold the tiles together, and partly so he can feel which piece connects to which.

It is definitely not perfect. There are things I already want to change. But it is real :) I can touch the borders, feel the relief, move from country to country, and use the Braille legend to figure out what is what.

I’m proud of it. I think he’s going to like it :)

Small update: his birthday is on July 12. I’ll try to write a proper follow-up after I give him the map. It may take me a few days, because I want to be present in the moment and not turn it into content immediately. I’ll share what I can :)

Six pictures of the map

descriptions of the pictures

Picture #1 - OOP stands with the four tile squares of the map displaying on a wall. The map shows a section of Europe (where Serbia is located) and parts of North Africa.

Pictures #2 and #3 - featuring four tile boards for the map and two tile squares for the braille alphabet and numeral codes

Pictures #4, #5, and #6 - references of the map to help assist with creating the 3D map. One picture features a normal displaying default map. Another picture shows a satellite layer of the map.

Editor’s note: OOP received tons of positive reactions, listing some for more significant details

Relevant Comments

Commenter 1: That’s amazing! It would be great if you make it public. Maybe so that people can 3D print it themselves?

OOP: Thank you! I actually have the code here.

It’s still a rough first version and the instructions need cleanup, but I’d love for people to use it or improve it.

Commenter 2: What an incredible gift and such a neat project to sink into

OOP: Yes, it was really interesting to make. The coolest part was finally holding it in my hands after months of designing it on the computer. It feels completely different as a real object.

And I think it will be even cooler when I actually give it to him. I don’t know how he’ll react, but after so many kind comments here, I’m waiting for that moment even more.

Commenter 3: It is an amazing map. It always strikes me the world looks so very different when a different country is in the centre!

OOP: A friend pointed out yesterday that if you take some paper maps and draw a horizontal and vertical line through the middle, they basically meet around the Balkans. So I guess we’re the center of the world after all :)

Commenter 4: You should consider reaching out to Clovernook Center for the Blind and Visually Impaired! They’re the largest producer of braille worldwide and have started dipping their toes into 3D printing and developing an online database for free 3D printable files. Some of their current files include maps and landmarks and they might love to add your files to their database. I’ve worked with them in the past and have nothing but good things to say.

OOP: I didn’t know about Clovernook, but this sounds very relevant. Thank you so much!

Commenter 5: This is AWESOME!!!! Well done!!

May I ask what is the purpose of the tile with the letters in Latin and in braille for your friend?

OOP: Good question. He actually doesn’t know Braille yet. From what he told me, Braille education is not very accessible here in Serbia.

So that tile is partly for learning. It lets him connect Latin letters with Braille symbols, and hopefully later use them to read things like capital names on the map.

Commenter 6: This is such a fantastic and thoughtful gift. Some of my work is in disability spaces (and I am disabled myself) and you came across one of the hardest walls I come across when working with nondisabled people : how we view pretty or nice doesn't always translate to functional and/or practical for the person with a disability. I love that you took those considerations in and made the map useful for him over what might seem "pretty" to a sighted person.

Love that you found such a great friend in a new place.

OOP: Thank you for your kind words. He really is a very good person. I think you might be the first person here to say something about him. Thank you.

Commenter 7: This is an incredibly thoughtful gift! You really went about it by thinking about how he experiences the world, and how he'd experience a textured map. It's just so beautiful all around. May you go the rest of your life without stepping in a puddle while wearing socks.

OOP: Yes, we spent a lot of time together, and I think I started to understand a little better how much being blind changes everyday life.

I think he taught me even more than Serbian. I got a good friend, learned the language, and also got a lot to think about.

Update: July 20, 2026 (2.5 weeks later)

A lot of people asked for an update, so here it is :)

Of course, my friend really liked it. When he saw the map, he was genuinely moved and cried.

He spends a lot of time with it, but honestly, the part he liked most was Braille itself. He had wanted to learn it for a long time, but he had never really had an opportunity.

So now we spend time together, and I teach him how to read Braille. It is difficult for him, but he really enjoys trying and puts a lot of effort and energy into it. And he keeps thanking me for being patient with him.

At the same time, there are quite a few problems with the map itself that I discovered while using it with him.

First, I used regular raised numbers on the map instead of numbers written in Braille. That is, of course, a downside.

Second, the dots on the Braille alphabet came out quite small and sharp, so they are difficult to distinguish.

I tried to use standard Braille dimensions and spacing, but after 3D printing, the result was not quite what I expected. Everything looked normal in the model, but by touch, the dots were not as comfortable or easy to distinguish.

Because of that, learning is more difficult for him, since the dots themselves are hard to tell apart. But he is trying very hard, and he is already making progress.

I think that in the second version of the map, I will take all of these problems into account and make it better.

Commenter 1: have you talked to him about projections? because I can imagine that is something that does not come across as very intuitive to a blind person, since most analogies for them literally come from visualizing maps.

OOP: My friend wasn’t born blind - he lost his sight over the past ten years, so he has the same basic understanding of maps and top-down views as a sighted person.

But if I understood your question correctly, yes, this kind of projection may not be intuitive for someone who has never seen. I spent some time explaining how the map works, what the different boundaries represent, and how to interpret it.

Commenter 2: Braille is such an obvious use for 3d printing, I hope the industry can figure out and advertise standards for different applications so it’s easy for people like you.

OOP: I think it’s worth looking into - there may already be some established standards or ready-made models. However, not every 3D printer can reproduce the required shape accurately; it probably depends on the nozzle diameter and print settings.

Commenter 3: I can’t imagine how difficult it is to map this in your head through touch alone. You’re both amazing humans

OOP: Yes, it takes him quite a lot of time, but he genuinely enjoys it. When I see him getting absorbed in the map and spending time exploring it, I feel that the whole project was worthwhile. For me, that’s the best reward.
