Christmas release for OS-Railway in H0! (1:87)

thingiverse

Marry Christmas to all 3D-printing nerds out there! :) I've gotten the question a couple of time - Can my designs in the OS-Railway system be printed in H0? (H0 is 1:87, and they are originally O-scale, which is 1:45) and I said no and promised myself not to try, in order not to waste time... but of course I could not resist the temptation at last. so here it is! a functional H0 (1:87) print of the Z70 locomotive and a freight car to go with it. This is the original Z70-design: https://www.thingiverse.com/thing:2146425 The OS-Railway system is intended to be a free, open and fully 3D-printable railway system. It is more a DIY/toy thing than it is a scale model railway, but I try to make most designs at least look reasonably scale like. The electronics in most locomotives is based on the ESP8266 wifi chip on NodeMCU boards. The board can be programmed using the Arduino IDE and is remarkably easy to use. For more information about this, click on the link to the Hectorrail 141 page where the electronics is described in more detail. This print in H0 is insane DIY level so do not try this unless you're know what you're doing! I will not do any instruction material for this one, as I'm already too late with lots of stuff here. I built the demo layout entirely in one day, so time is super tight! If you are unsure and want to try to print train stuff, start with the original OS-Railway stuff in O-scale which is much easier to use. I've included two modified versions of the chassis: 1. Frist I tried making my own gearbox for a small simple 10mm motor. It "sort of" works. The shafts used are 1mm carbon fiber rod. For this gearbox to work, it's critical that you sand of every smallest little artifact left from the printing process. Especially on top of the gears there is usually uneven spots. 2. When I wasn't satisfied with the homemade gearbox, I moved on and used a motor from maxon, an RE6 with a planetary gearbox with 57:1 gear reduction. This is much easier to get to work, although of course much more expensive. Both these versions use 1mm carbon fiber rod as wheel shafts. The track is my standard track from the latest release, scaled down to 51,7% so if you want to print individual pieces, just go to the track page and scale down any track you want, although I suspect getting the turnout to work will be an insane challenge! Track: https://www.thingiverse.com/thing:4408535 The electronics is based on the same setup as in the Hectorrail 141, and with a bit of squeeze I managed to get it all in there together with a 2S lipo 260mA! but it was TIGHT!.

Good luck with the project! :)
