To print this model, you need about 2.4kg of filament of different colors and types. Most parts can be printed with any type of filament, such as PLA, ABS, PETG, but tracks must be printed with flexible filament! Therefore, your printer must be able to print with flexible filaments! More information about filament types can be found in the printable parts list:  Here

All the necessary information for building the model, such as a list of non-printed parts for purchase, a list of fasteners, some characteristics and features of the model, you can find in the assembly instructions for this model: Here

In the archive with the model, you can find individual parts as well as parts combined into small groups, which will help you simplify the process of preparing parts for printing. Some print groups are too big for 180x180mm printers, so if you have a printer like that, you need to print these parts from individual parts folder! Some individual parts are too large for 180x180mm printers, so you will need to print these parts from the Alternative Parts folder.

The archive also contains some alternative versions of parts for printers with 300x300mm print area. Some parts are combined, which will simplify the process of assembling the model!

All parts for the model are designed to be printed with minimal using or no support material. Check out the printable parts list at the link above!
