About us

Helping your favorite game be on the table more often.


MitroCZECH BoardGameHolic

Our inserts and add-ons are designed by the player for the player. They are created right at the game table and Jeník's main goal is an insert that makes it as easy and quick as possible to prepare the game, clean it up and serve during the game itself.

How our inserts make it easier for you to play

The goal is simple: more playing, less preparation. We test everything in real games - tweak, change, replay.

Quick start without the chaos. With components sorted by prep/expansion/player progression into clear bowls and boxes, you can handle setup and cleanup in minutes.

Clutter in the box and on the go. Every component has its place and we even allow for vertical storage. So everything fits together and nothing spills out in transit.

Game games safe. Overlaye keeps chips and progressions on the scales where they should be - even if someone smashes the table, it won't ruin your game.

Overlays? Sure! For products, we list the size and thickness of the wrappers they are prepared for, but they also fit unwrapped cards. The vast majority of inserts already allow not only for these, but also for extensions and promo cards.

Customized to your table and taste. Need a different height, color or club logo? Contact us and we will customize a product for you.

Because of MitroCZECH

From the player for the player. Everything is created right at the table - we prototype, we play, we debug. Every design is tested in practice, not just on a monitor. We don't make boxes within a box and replace zip bags with plastic, we create fully functional and multi-use storage systems with each game in mind, how it is played and what the player needs while playing.

We bring interesting and unconventional inserts and other Czech and international designers to the European market, meeting the growing demand for an ever-expanding portfolio of board games.

Community tested. We listen to players and reviewers to make inserts more versatile and thoughtful.

Materials & Printing. We print primarily from PLA and PETG on Prusa and Bambu Lab printers - a balanced mix of precision, strength and appearance.

Ready to carry. We're also tackling the details: fixing the boxes with rubber, more durable lids, clear signage - to make the journey to game night stress-free.

After-purchase support. Mismatched part or missing part? We'll send a replacement or modify the model. We are a teammate, not just a vendor.

How we work together

1) You have a game and you choose insert or add-on for it. On the product page you will find what fits in the box (base, expansion, promo cards...) and tips for use.

2) Do you need customization? Send us the dimensions and let us know your idea. We will design a customized solution and fine-tune the details together.

3) Print, proof, ship. We will print, proof and package carefully. Then just deliver and play.

Our story in brief

2019 - First experiments with 3D printing for parts for Mars: Teraformation. Enthusiasm is the new obsession.
2020 - First custom inserts are created (Cartographers, Splendor MARVEL...). Goal: to make them gamefully and visually satisfying.
2021 - Switch to Prusa printers, color printing. Start working on the insert for Duna: Empire, which we're tweaking month by month. Set up an Etsy shop BoardGameHolic to offer print data to other players.
2022 - We launch a Czech e-shop MitroCZECH.cz, set up a small 3D printing farm, start working with our first external designer. An insert for Ghosts of the Island is created. Orders go to Europe, America and Asia.
2023 - Jeník leaves his job and 3D printing becomes our new main income. We start supplying inserts to specialty board game stores as well. We start working with CGE. We expand the farm with Bambu Lab printers and start building a new office.
2024 - We move into our new office. Local TV is doing a story on us. We start taking a booth to board events and meet lots of customers in person and make new board game friendships.
2025 - MitroCZECH BoardGameHolic s.r.o. is founded and we establish cooperation with other shops, board game publishers and designers from the Czech Republic and abroad. 
DNES - We still design, print, test. And above all - we help your favorite game be on the table more often.

Frequently Asked

Do your inserts fit on wrapped cards as well?
For most products, yes - for each product, we specify the thickness of the sleeves the design is made for. If you are unsure, please email us.
How long does printing and delivery take?
It depends on the size of the order and the workload. For products we give an approximate printing time. If you're in a hurry, let us know - we'll let you know what we can do.
What if something doesn't fit?
We're teammates - we'll modify the model, send a replacement part, make arrangements. The goal is to make you happy with the result.
Do you also do custom 3D printing, outside of board games?
Yes. Do you need a holder, a prototype, a small series? Enquire about custom 3D printing.
What material are you printing from?

We print mainly from PLA and PETG. PLA is precise and good-looking - ideal for internal binders. We choose PETG for more demanding parts (lids, overlays). We tune everything to fit well in the game, easy to use and look nice.
