I am looking for a servo holder that fits in the slot on the back of my Accucraft Mimi Ruby. I can’t find one anywhere. If someone has a plan to build one, that would be great too. It would have to be built to withstand the torque of the servos. Thanks in advance.
There used to be a guy making them from aluminum, and his web page (rc-steamers) is still operating: https://www.rc-steamers.com/
HOWEVER many folk have been trying to find him or a kit for the past year or two, so don’t waste your time.
I post this on the hope that someone will look at his ‘kit’ and reproduce something similar.
Very clever and efficient design. A single 3DP part with threaded inserts, plus servos and hardware.
Bummer that it was “temporarily sold out” 3 years ago, and the page was last updated 21 years ago.
Sounds like a business opportunity Cliff. Get printing!

As it is in a live steamer, I wonder if 3D printing will handle the heat? Didn’t those commercial print guys handle metal printing?
It also occurred to me that I have lots of ‘standard size’ servos from china with metal gears that are probably smaller than the ones he used?
Pete, if temps go over 150F back there, it could be printed in a high-temp resin or filament, both of which can be good for 400F or more. But I’d wonder about the plastic servo housings surviving… Maybe some temp readings would help.
Not sure about the serov’s gear material or size, one would have to do some research and guesstimating the dimensions from the photos I suppose… The ad says “micro servos” so perhaps that means between 5g and 7g? Not sure.
Yeah, I’d need some time, and a Ruby though… 
The latter isn’t much of an argument though, since Linda was really inspired at the GLTS show about getting her own kit, either a Regner Heisler or Accucraft Shay… and even suggested me getting a kit as well. Research on loco options and lottery-winning in progress… 
Cliffy, I’ll remind you that lots and lots of live steamers have r/c servos fitted in them. I personally have had at least a half-dozen over the years.
I haven’t seen one melt a servo yet!
I’d be more concerned about the rigidity of the structure holding the servos? For anyone bemused by this discussion, here’s a screen shot from his website. It’s really very clever:
Nor have I, though I’ve seen a number of servos in LS locos. I was merely trying to answer your comment about filament withstanding the heat. For rigity, if one knew the temps involved, some testing with a toaster oven should clear that up.
