3D Printed LKM NS2f

That is a nice looking loco. Quite interested in the jackshaft and cranks, did you end up with any tight spots that needed attention or did everything just fit right off the printer? I've not attempted a loco with con rods, but looking at this I think I am inspired to incorporate con rods on the next one.

You mentioned you were looking for a source of gears, this place has quite a selection: https://www.technobotsonline.com/gears- ... ckets.html
Quite cheap too, you can get a 10pk worms and 10pk plastic gears for £2.61. 50 3mm shafts for £6.55. 10 MFA RE-280 motors for £15.48. Total £24.64, or £2.46/chassis. Combine that with a 3D printer and you have a recipe for more locos than you can fit in your shed. R/C ends up being the most costly part...

Also, the pictures don't show up properly here either. I think its because the forum is using HTTPS and the pictures are served without HTTPS, and Chrome doesn't like that for security reasons. Your image host doesn't seem to support HTTPS.

The con rods were a little tight in places, but a small fettle with a 2mm drill bit soon sorted that out. The quartering method is built into the axles and the cranks, it worked very well indeed and I had no idea if it would work, hence not posting anything about it until it was finished and I was confident it worked as expected.

P.S. Thanks for the link I have ordered some to try

I CAN see the photos, and it looks good to me, and a good example of what can be achieved with a 3D printer

Thank you for your kind words

Great looking loco, Steve - after all those shenanigans! Did you use sketchup?

Rik

Hi Rik. Glad you eventually got to view the pictures. I used Tinkercad for all the CAD work, takes some doing and is quite restrictive, but very very easy to use compared to any of the proper CAD programs.

Yay! Three cheers for TinkerCAD
Here's my latest TinkerCAD tinkering.

Like most of my modelling, the detailing is representative rather than perfect scaling, but I know it will print without the need for further tweaking.

Hi Rik

That is some detailing for Tinkercad, wow, I am impressed!

Thanks Steve. I'm only scratching the surface of what's achievable. You only have to look at the gallery to see what some people have produced. For example ....

I have updated the pictures of the original post as most people could not see them.

I have actually printed a few of these off now and made design improvements along the way. I shall post some pictures up of the changes later today hopefully.

Any chance of sharing the file Steve.

Sorry I can't share that one as I am selling it commercially as it took weeks to design, test, redesign etc. I do sell the the complete kits but not the files.

Oh well never mind...I thought I could have a go at printing a loco and see how I got on with it....Back to fumbling along with 3d printing then....

Thingiverse has a 3D printable loco on it, various versions and modifications have been done to it as well, just download them and print away, that's all I did at first. That one is far simpler to print and build than mine

Thanks Steve, I will give it a go.

Don't suppose there would be a steamer on there would the. Must have a look later...

Rod,
Both Rik and I have written extensively about our builds and mods of that Thingiverse loco. Just do a search.

Not that I have found and I have look quite extensively.

Dunno if it's any good and it seems to be a weird scale (18mm gauge) but if you want to play about with the scale and design a proper chassis it might be ok.

Will look at that Philip, thank you.
