The first steam locomotive

The first steam locomotive by Richard Trevithick
Completely remodeled my original model in the new program, more accurate, more faithful to the original with the option to insert a motor and have a movable version

 I am attaching photo instructions for assembly, the instructions are also in the video on Youtube

You will need:     Motor N20 DC 30 rpm,
                                   Bearing 10x5x4mm 8 pieces
                                   Bearing 6x3x2.5mm 8 pieces
                                   M3x30 2 pieces
                                   Brass wire diameter 3mm, length 135mm 3 pieces
                                   Brass wire diameter 3mm, length 8mm 4 pieces

Some parts need to be glued, it is stated in the instructions.
Some holes need to be drilled with a drill, this is also in the instructions.
I also prepared parts for the motorless version, you simply use an adapter instead of the motor.

Bearings 10x5x4mm are used for the wheels of locomotives and carts, and bearings 6x3x2.5mm for moving arms.

On the chassis parts, cut a hole for moving the battery box cover

For parts 1 and 21, it is advisable to use a collar so that they do not come off for printing

For the non-motorized version, print out the non-motorized wheel and non-motorized adapter part, insert it instead of the motor and use the 10x5x4mm bearing

You can put caps on the wheels - Locomotive C9-4x and trolley C8-4x
If I have forgotten something in the instructions, or if something is unclear, write to me, I will be happy to advise

I also prepared a stand under the Locomotive so that you can comfortably see the work and movement of the parts and not have to push it across the floor
