One of the only downsides to running the Y rail modification on an AO-10x is that if you ever have a flat piece of something detatch and fall on that rail, it can apperently manage to wedge itself between the rail mount screw heads and the rail carriage itself. Needless to say this is a BAD THING to have happen to your printer at full speed. So, in order to prevent that I plan on fitting my machine with a way cover. As I don’t think they make one for this particular rail type, I’ll be making my own out of a sheet of mylar CAD plotter paper.
At the same time, I also think that a way cover floating in space looks silly, so I went ahead and cut and folded some top plates out of thin plate aluminum. As I have a modified and widened machine, I’m not going to list the dimensions unless anyone particularily wants them since your machine will most likely be narrower, but they were easy enough to make out of two sheets of 24 x 6 aluminum sourced from Home Depot for $9.00 ea, and bent with a piece of junk $20 harbor freight metel brake. I’ll have another $5, maybe $6 in mounting hardware by the time I am done.
The way covers themselves will be free, but they will take about 3 hours each to fold. Once I get closer to the folding part I’ll post progress and method pictures of that as well.

which i have used before for some of my CNC ways, I generated an AO-101 - mendelmax-ish Y rail cover file. We can’t upload PDF’s here so I uploaded it as a txt file. you will need to rename it. Print two of those on a sheet of mylar, then follow the instructions at the above website to make your own. You can paint them black with plastic spraypaint when you are finished for additional decoration
Here are the cover plates. They will also get a series of holes around the mounting edges at some point. I will have to take off the heated bed mount plate to get them to fit. I’ll also need to relocate my Y rail endstop, which I plan to do anyways to later make room for moving the Y motor inside the frame. Eventually the power supply, control box and a few other accessory switches will go under those plates as well (gantry and nozzle lighting, case fan, etc)
I still need to find a foot mounting bracket that I like in that scale for mounting feet. all the ones I normally use are too big.
Front and side plates will also eventually occur. those are mainly waiting on my Z rail project to finish itself so I can cut them accordingly.
