THE100 (v1.0) Ender 3 bed mod - Remix

When building a the100 printer, I had issue finding an Ender 2 bed or similar, so when I found a very cheap Ender 3 one I decided to install it based on the mod by overgo.

I had to make some changes: my the100 version has only two rods in the front (and printed columns in the back) and I haven't any metal bracket to hold the bed. Plus, the bed I purchased has a switch to turn the power on and off in one corner, so I also had to further modify the top parts based on that.
I modified the design of all the bed components trying to keep the center of mass in the middle, that's why the right and left brackets are slightly different. 
Be aware also for the bed screws, for both length and diameter.

Make sure to check everything with your own components, better if with a 3D assembly with accurate data (weights, dimensions, etc).

I added some cardboard under the bed to insulate the PLA parts a bit better; I sometimes print PETG and I feared the heat, I don't actually know if that's necessary, but with a bed this large and no prior knowledge I preferred to be safe. So far, I found no issues at all. (UPDATE 07/09/23: everything is still working fine after hundreds of hours of printing!).

I won't upload the top frame parts until the release of the new the100 version (v1.1), the back columns are similar but not publicly available yet (check their Patreon for it), refer to the original mod for them.
UPDATE 07/09/23: I uploaded the step file for the top frame assembly ("2B3D_Top-Frame_assy"). I don't know if it's compatible with the v1.1 version since I haven't check it yet, but if there aren't any major changes in dimensions, it should be. Please check before printing and adjust the model to your need (holes, interferences, etc). You may need to design or adapt the back columns.

As per the printing tips, follow the the100 suggestions: PLA with 0.25mm layer height, 0.5mm line width, 3 perimeters, 3 top/bottom layers, 30% grid infill. Use supports from the bed for the two brackets.
Print some test files before to check your printer's tolerance (the bearings has to fit perfectly!).
I personally used a 0.32mm profile and PLA with no issues.
