In the download their are several PDF files. The ones that have "HOLES" in the name will give you the dimensions of the ply wood. but for quick reference its 23.88" x 23.88" x 11/16" thick. Your supplier may sell it listed as 24 x 24 x 3/4" or something called "Handi-Panels" its basically the same thing, as long as your holes all come from the same corner you should be good to go.

I don't, however i believe all the models were provided as STEP, even the full assembly. Even though I'm not a huge fan of it you could use edrawings from solidworks to view it and it you should be able to get all the info from that. Ill try and post a bill of materials in the next day or so.

the model?

I've thought about different ways to do it but haven't settled on anything I truly like, one idea I did have was to put just a single row of drawers in the center and have the units pivot out from the sides, I've thought about putting the whole thing on a lazy Susan and having the second unit in the back. What I'm not brave enough to try is making the unit taller. If I did that I would probably make this a whole table and have the two units on rails under a bench.

you use an m4 x 12mm lg socket head cap screw and a jam nut ill add a photo of a section view of it

with the AMS off the bottom plate you can assemble the top to the bottom, put the other grommets and feet brackets on the top plate and verify the printer sits nicely. take the printer back off put the stand where you want it install the printer and AMS, and run the feed tubes from the AMS to the print head. if you don't install rubber feet of any kind on the stand you will want to secure it the table some how, i threw a screw in mine to keep it on the desk, otherwise it will walk off on you.

if you are using the modified drawer rails you wont need the bearings installed in the u-shaped bracket that goes on the AMS. I took the rails apart, installed the u-bracket on the AMS then loosely attached the rails to the AMS bracket. Once you have the bracket sliding nicely you can separate the slides again.

At this time I don't, the full assembly model was uploaded with all the other files. you could open it with some free software like e-drawings. I can walk you thru anything you may have questions on. I started out by pre-drilling all my holes in the two wooden boards then assembled the two uprights that hold the drawers and attached them to the underside of the top plate then the mid and rear supports went on the top plate.
