Steam Toy Train

This is my next design for my nephew. It's similar to my previous design https://www.thingiverse.com/thing:3338151 Print the roof for the locomotive and the person car with support on. Assembly Instructions ===================== Connector ---------- I use a neodym magnet with diameter 10mm and height 3mm. The head is an 11mm decorative nail (Polsternagel) with the pin cut off. A 5mm long brass pin with diameter 2 mm helps to glue it to the base. Alternatively, you can use 8mm magnets (BrioBumper_8mm.stl). Wheels ------- The wheels are made with brass tubes of diameter 2mm and wall thickness 0.3mm, 9 mm decorative nails (Polsternagel), and some 2 component epoxy glue under the head of the nail and inside the tube. Make sure that the wheels have enough distance. The inner distance between the wheels should be about 22mm. I use two 1mm shims when I mount the wheels to the base. Alternatively, you can use the file wheel_plastic.stl and a 2mm diameter brass rod of length 29 mm only. Bogies --------------------- Use an M3x12mm socket head screw to mount the bogies on the car. Directly turn the screw into plastic. Be careful when doing that and make sure that the screw is perpendicular and do not screw it in too far. The two bogies are aligned with two hock screws 2x20mm (sometimes they are labeled 2.3x20mm).
