[Luke Towan] has a cool HO scale Escalator mostly made of 3D printed parts, with some laser cut acrylic, for a station on his HO model railroad.
Escalators are mesmerizing to watch – there’s something magical about the stairs unfolding at the bottom and folding up at the top. But they’re very hard to model.
[Luke Towan] has done it – his 3D printed version closely resembles the real thing mechanically. Pins are carried around, cantilevered out from a 3D printed chain. A stair swivels on each pin – at the bottom each stair’s free end rests on a ‘bottom’ far enough down for the stairs to be level, while on the incline the ‘bottom’ is just below the pins. It’s a tricky build.
If you like pushing the envelope of what 3D printing can do this is an interesting project, even if you’re not planning to build an escalator. There are lots of tips for making small mechanisms with 3D printing, and for making small mechanisms that work reliably without stuttering.
He’s not the first to build an escalator. Back in 2015 we covered this wooden escalator for slinkies, and just recently this 3D printed version from [AlexY].
it is “H-zero” not “H-oh”!
awesome work nonetheless!
@piachoo it’s Half O, because it is half the size of the O scale
True,
and N scale is half of HO scale.
So it’s the HOHO scale?
Indeed you’re right mate. At first I though that HaD embraced Ebonics, sadly I was disappointed.
Oh is also used instead of zero in the english language, depending on the region (GB, AUS)

Zero is lazily pronounced by Burger friends as “Oh”. Remember a Zero day exploit is also an Oh-day. So I give our american friend the benefit of doubt he intended H0.
Pretty sure the video creator is from somewhere in australia, not the US
Surely it’s “HO HO HO” at this time of year?
Somebody clue me in on why Half-O would be pronounced H-zero.
O scale / O gauge, not 0 scale / 0 gauge.

German Märklin H0.
I was also confused by [piachoo’s] comment, since I’ve always known this as HO scale (although I confess to being ignorant of the origin of the names of the various gauges).
German here, it’s “H null” for us, we don’t have that many terms for the number 0, just “null”. The letter O is just in English synonymously used to the numeric digit 0 (zero/null). And it’s the “Nenngröße 0” not “Nenngröße O” for us. It’s primarily numeric. The predecessor to 0 was 1.
Hi, another German here. I second this. 🙂👍
“Null” is also used in English language sometimes, I think.
So if H-Zero is too tongue breaking to use for native speakers, there’s another alternative, maybe. 😂
In computing:
“The null character (also null terminator) is a control character with the value zero.”
https://en.wikipedia.org/wiki/Null_character
Funnily, there’s a null device in Unix that’s “not to be confused with /dev/zero”.
https://en.wikipedia.org/wiki/Null_device
So Englisch language is able to make a difference – sometimes, at least. 😉
I just leave this here: https://en.wikipedia.org/wiki/Talk:HO_scale
There might be a xkcd post about this as well, but i’m not shure
“Burger friends?”
A term of endearment for their enthusiasm of fast food.
Does it work in reverse? He could have a little Trump.
You need a miniature Trump to ride down it and recreate an infamous moment in history!
Not an accurate model, it’s missing the component that eats Chinese families when they get to the top.
I wonder how similar the mechanism is to full-size escalators.
What? No moving handrail?
B^)
“Escalators” ? Oh, that’s a working miniature of moving staircases! Cute. 😍
That is a beautiful model. It is an impressive achievement to design and make that.
I can’t believe he used tinkercad to design all of that.
My biggest print was a 55″ long 6wd 1:14 scale RC semi truck. Next I was gonna make a 50 ton rotator tow truck. Maybe I’ll do this first. I see used resin…can it be done FDM?
