2.5D Red St.Petersburg Metro Train

thingiverse

This is a 2.5D model inspired by the new red trains in the St.Petersburg Metro. The model uses 3 or 4 colours, but it is designed to be printable on a single material printer with a bit of manual fiddling. After slicing, edit your gcode files to insert filament swap commands, for example: ``` ; -- filament change to white -- M104 S195 ; set temperature M600 G1 Z2.400 F7800.000 ; move to next layer (7) G92 E5 ; reset extrusion distance ``` Make sure that your extrusion distance matches that on the next layer. For example, if it begins with something like ``G1 ... E5.01406``, G92 E5 will likely work. If the values of E mismatch, you risk getting blobs of filament injected in the middle of your print. Print the body and the wheels + window inserts separately. If the parts don't hold together by friction, glue them together, or use the entire set as a puzzle. P.S. At the time of printing this my extrusion multiplier was uncalibrated, sorry about that.
