Here are the parts for my Mammut (mammoth) printer. It has a moving bed, which I was sceptical about at this size, but it works great. The reason I tried a large moving bed was to use stuff I had lying around that would lend itself to that kind of configuration. I now run two motors on the Y-axis for extra power.
I will not provide detailed assembly instructions, so don't start building iit if you don't feel that you can do it on your own. It should be self explanatory to experienced makers using the pictures provided. You may need to change some things to suit your part selection in case you don't have/can get hold of the same stuff. Just do it.
The part file includes all the parts in one file, so you don't have to download fifty different files.
The bed is made from a 40x20x2mm aluminum rectangular tube, split in half along the length, and five 90° angles. The surface is a sanded 4mm acrylic sheet, 800x520 mm.
The parts include a holder for a smart controller LCD display (mine was from Sunhokey) and a MKS Gen V1.2 controller board with A4988 drivers. The Newest version is V1.4:

The pulleys are 2mm pitch. I use them with GT2 belts with no skipping despite being printed:

The linear bearing blocks take 3x10x4 mm ball bearings. A total of 28 bearings is needed:
https://www.banggood.com/10pcs-623-ZZ-3x10x4mm-Deep-Groove-Ball-Bearings-Miniature-Bearings-p-81182.html?p=HD240528697332015103
The linear rails for X- and Y are 3/4" (or 19mm) stainless steel tubes. I'm sure other rods or tubes in other materials will work as well as long as they are 19-19.05 mm (3/4") thick. 2x700 mm and 2x1220 mm are needed.
The rails for the Z are 500 mm long SBR16 supported rails, with four LME16UUOP bearings. These bearings are the 26 mm outer diameter kind, and not 28mm:

The frame is made from plastic gussets and 40x40x2 mm square tubing of the following lengths:
2x1300 mm for the lengthwise pieces.
3x620 mm for the ends and top. The ends would benefit from being made from steel instead of aluminum.
2x500 mm for Z. These are installed on the side frames at a distance of 390 mm from the front end gusset, as one photo shows.
2x500 mm long 8x8 mm lead screws with nuts are needed. They will fit into the Z shaft adapters:

I use a chinese E3D clone with a home made Volcano hot end. The fans for the hot end are 40x40 mm for the cold end ccooling, and two 35x10mm blower fans for PLA cooling:

This fan can fit with some modification:

I use 92 oz in/65 Ncm steppers for X, Y and extrusion, and smaller motors for Z. The 30 tooth pulleys on X- and Y need strong motors, and allow high travel speeds of up to 300 mm/s.
A ~11 mm extruder gear is needed:

X uses a microswitch for homing. Y and Z uses PiBot optical end stops for homing. Parts are included for installing all switches. X- and Z-switch brackets are attached to the frame with high strength double sided tape and provide a large enough contact area to give a very secure attachment:
