Are thes files (STL or other ) somewhere available?
ohhhh snap, those are sweet. Might have to talk someone into printin’ me one some day!
are there STL files for these somewhere, they aren’t on github?
I guess this could be them?

Just checked, files are not on Git.
sorry will get them uploaded tomorrow

were you able to get them uploaded? I just looked on git and grabbed the zip from here and didn’t see them.
-thanks, Dave
Here is the situation: The default plate on a c beam axis is 80x80mm with 4 internal rollers about 40mm apart. This is sturdy for small routers, but for big 9 lb routers like the ridgid r22002 not very sturdy IMHO. So I have been working on a plastic clamp that wraps around the Cbeam to help reduce play when using the 3.5" and bigger diameter routers.
However I think the best solution will be to use a larger gantry plate which is 125x125mm with a stance of 80mm between rollers keeping it more steady. Once I do some testing I will release these files. I do not want to put files out that do not work well 
And most of these plates have four mounting holes using either 6mm or 1/4-20 machine screws. So one will need a tap to attach them to the aluminum plates.
Using a 0.8mm nozzle and .5mm layer height 40% fill it takes about 8 hrs to print on a cr10. I wuold not recommend using a lower fill. And one must print in the orientation shown so the layers wrap around the router. if one prints it vertically the “grain” would be weaker.
I still need to 3d print this file to make sure it works good. for 3.5" routers.
it is designed to be used on the 125mmx125mm sq gantry plates. the four mouting holes line up with the 5mm threaded screw holes on the gantry plate so very easy to install.
I’m no 3D printer expert but I’ve been doing more research lately and is that level of infill really necessary or could you get away with less fill and more perimeter layers? I’m really ignorant on the subject and just trying to learn.
This video had me thinking about it and any Maslow application is a real world application I am interested in. Thank you!

That’s one of the best actual tests I’ve seen. If I got it right perimeters are more important than infill, infill patterns can matter, and high infill percentages don’t help much. Like a lot of things overkill isn’t helpfull.
Part strength has been discussed a lot, and adding tiny pinholes to get extra perimeter plastic in critical areas can help. Some have left holes and filled them with hot glue. Somebody must have dug out their favorite structural analysis program, must have been a master’s thesis on it somewhere. I seem to remember one of the slicers mentioning built in structural analysis in the future, but not which one
Oh boy, a built in structural analysis seems like it would be the bees knees! Perimeter being more important than infill percentage is what I got from the video also. A friend of mine shared that with me and I found it very interesting. When I get my 3D printer I will definitely do more perimeters for strength and less infill. Glad you found it interesting/helpful!

Metalmaslow,
Could I ask you if you still have the stl files that were the subject of this post? I would love to give them a try on one of my printers.
Thats great, i just finished assembling my “Prusa mk3s” yesterday night Still struggling with some stringing but otherwise it seems to be doing well…
