Terraforming Mars - player board holder

I was recently looking for a model for the game board of Terraforming Mars that I could print on my printer (A1 mini). Unfortunately, there are not many good options so I decided to create a remix of two models that caught my eye. I combined the best (in my opinion) features of both of them to create a sturdy, easy to assemble and (most important) lightweight model. I hope you will enjoy it and have lots of fun playing and printing it!

The first of the models I told you about:

The second one:

P. S.
Personally, I needed to use pliers to join the plates, but it's a one-time operation, and it holds incredibly tight.
