This thing include 2 models for the simply daily plan for you kids/family/class.
You can print as much items as you need.
I printed just one train car for the daily activity like shower, dinner, playground and so on. All the notes are made by my kid (it was soo much fun with it). Now when we don't know what to do with the rest of the day, we just put cars one after another and remove them when task is done (like on the picture attached). Sometimes I use it for myself daily tasks or just as a reminder for every week day. Also you can stick magnetic tape to then and put them on the fridge :)
I use PETG filament to print them just because it is a little more stretched than PLA.
The train cars may be assembled and disassembled many times (just push to click).
PRUSA PETG (but PET should be ok too)
I used PETG filaments just because they are more flex and stretch. I tried also with PLA, they are working well, but the PLA may be damaged easier that PETG.
