F1 Calendar 2026

I designed this modular F1 Calendar with all the Circuits and Dates. All the Circuits and Dates are on sliders so you can easily switch them around next year and print the new Dates. There are also indicators for Sprint Weekends and F1 Acadamy Races (the blue F1 Logos). And the Next Race Batch is Magnetic and can be put forward on each Circuit.

Print Instructions

Main Body

There are two versions of the Main Body. The non split Main Body is quite large at 325mmx325mm and wont fit on all printers. Because of that i made a split version. If you plan on printing the split version you would need to print all 4 models in the Main Body Split folder.

EDIT: added a bigger Tolerance Version of both the split and the non split Version. It has 0.2mm more Tolerance. I also added a Test Print for both Tolerance Versions to test it before printing the big part.

For mounting the Main Body there are two options, you can either mount it with the 4 countersunk holes or you can put it on any magnetic surface.

As for Print Setttings, i printed it with 0.2mm Layer Height, 15% Infill and 3 Perimeters

I printed the Main Body in Polymaker Polyterra PLA Cotton White

Circuit Slider

The 24 Circuits Sliders are in the folder Circuit Sliders. You would need to print each of those. 

There is one Color Change on the Circuit Sliders at Layer 27 (4.1mm Height). If you dont have a MMU or a Prusa XL you can easily do it manually. Just slice the Models and then pull the Slider on the right side up and down until you find the right Layer. Then right click on the slider and add Color Change.

For the Sliders i used 0.15mm Layer Height and 15% Infill

I printed the Sliders in Prusament PLA Galaxy Black for the Black Body and Polymaker Polyterra PLA Lava Red for the Letters and Tracks.

Date Sliders

The 24 Date Sliders are in the folder Date Sliders. You also need to print each of those.

The Date Sliders are trickier to print. I printed mine on my Prusa XL 5T and used Red for the Date, White for the Sprint Label and Blue for the F1 Acadamy Races. If you dont have a way of printing Multi Color you can also easily print the Date Slider the same way as the Circuit Sliders with only one Color Change. Then the Date, Sprint Label and F1 Acadamy Logo will all just be one color.

I used 0.15mm Layer Height and 15% Infill.

I printed the Date Sliders in Prusament PLA Galaxy Black for the Black Parts, Polymaker Polyterra PLA Lava Red for the Red Parts, Polymaker Polyterra PLA Cotton White for the Sprint Text and Polymaker Polyterra PLA Ice for the F1 Acadamy Logo.

Year Batch and Next Race Batch

The last two parts are the Year Batch and the Next Race Batch to keep track where in the calendar you are.

The Year Batch gets printed the exact same as the Circuit Sliders. Its just one Color Change. And i also used Prusament PLA Galaxy Black for the Black Parts and Polymaker Polyterra PLA Lava Red for the Red Parts.

EDIT: added a Split Version for the Year Batch so the Logo doesnt have to be printed new every Year. The settings stay the same for the Year Batch, it is just split now. So you just have to print either the Year Batch non Split file or the Split Year Batch 1 and Split Batch Year 2 file.

I printed the Year Batch with 0.2mm Layer Height and 15% Infill.

For the Next Race Batch the file will be in the folder named Next Race Batch. You will need a 6x2mm Magnet. This Magnet is embedded in the Batch. And you will also need to print the Magnetholder simultaneously with the Batch. You will need to slice the Model and then pan the Silder on the right side up and down until you find the Layer just before the hole gets closed up. This should be on Layer 23 (3.5mm Height). You then have to right click the slider and add a pause. After that youre ready to print. While printing the Magnetholder should be finished before the Pause so when the printer pauses you can take the Magnetholder out and insert a Magnet. Make sure you have the Magnet the right way around, the open side of the Magnetholder should stick on the Tracks of the Circuit sliders (i have put some Pictures up). Then insert the Magnetholder in the Next Race Batch, make sure you cant see the Magnet anymore. After that resume the Print. The last 3 Pictures show the Process and how to orient the Magnet.

I put a presliced version for the Core One and one for the Prusa XL in the folder to use or for looking up how i did it. 

I also used 0.2mm Layer Height and 15% Infill for this Print.

And the Black Parts are also Prusament PLA Galaxy Black and the Red Parts are Polymaker Polyterra Lava Red.

Assembly

For the assembly of the Calendar you will need a couple of Magnets. The Magnets should be round with a diameter of 6mm and a thickness of 2mm. They are the same as for all the Gridfinity Bins. I added a Magnet to each of the Date/Circuit Sliders aswell as to the Main Body. But it would be enough to only put a Magnet at the end of each row to stop them from falling out. Just keep in Mind, that you would have to put a Magnet in each Circuit Slider for the Next Race Batch to work.

You then have to sort the Sliders and put them in the Main Body in the right order. I just looked the order up on the official F1 Website under Shedule.
