Description

Köf II version 2 compatible to IKEA, Lidl or Brio wooden train systems.

The whole model can be plugged together and will be fixed with 4 screws: 2x M2x5mm 2x M2x18mm

The wheels can be put in a metal 2mm shaft with a length of 30mm. The wheels wholes may need some drilling, so the shaft is not locking the wheels.

A complete guide how to assemble will follow soon!

I had no issues with the print profile. The pictures show the engine with the black parts printed in PETG.

Replying to @schreinerman :
Again, thanks for the great work and to reiterate: My comments were not meant to criticise your work!. I am looking forward to making the BR 218 next :D Regarding the wheels, I just make new ones in CAD following your design and exported them with a tighter mesh. Now they are as round as it gets, but I hadn't considered the z-seam. So there is still one bump per revolution... Regarding the side panels, I think a solution could be to space the longitudinal stringers, for lack of a better word, further apart by 0,2-0,4 mm.

What a great little model, highly recommended and easy to built.! Thanks a lot for sharing. Here are some things I noticed when printing and assembling the engine: - The wheels are a bit "polygony" in shape which makes them roll a little rough. - The cab side panels were not fitting properly, they were sitting too high. To fix this I rounded the edges of the chassis with sandpaper to allow the cab floor to sit on it without a gap. Additionally, I rounded the lower edges of the cab side panels. - When I pressed the magnets into the couplings they were not strong enough to pull a car. The issue was that the magnets were not fully pressed in. It a considerable force to squeeze them all the way it. But afterwards the couplings work just great. - For the next iteration I will glue the buffers in place prior to assembly. I found it a bit fiddly to get them aligned nicely when the engine is assembled.
