Scale: 1/87 (H0)Printing technique: FDMDesign: imagineryPrinter size: small eg. Anycubic i3mega (220x220)Note: You can also print element1 and element2 on a 220x220 printer,positioning it across the printer's build plate (picture6). I recommend printing the parts individually to avoid the issue of retraction (stringing).Note: If you are going to use marble filament to print element1 & element2 of the model, remember to make sure the filament is matte!To achieve a 20-degree track curve, please use flex tracks.
